The hairs on the back stood to attention, chest was fully pumped and ears pinned back; was it another full moon to deal with, no it was round one.
Footy is back and so were Roopena with a blistering display of football at Memorial Oval on Saturday afternoon.
The game got off to a flier with South kicking with the aid of a two goal breeze and had all the early going, South captain Ryan Baker was finding plenty of space and the signs were looking good for the Demons early, but they just couldn't get the score on the board.
Against the run of play Baker's counterpart Greg Fiebig read the ball off the pack and ran into an open goal to draw first blood for the Roos and kick start them into gear.
New recruit Matt Oliver kicked truly from a set shot in front of the score board to get the Roos second after some slick movement through the midfield.
Greg Fiebig, who two weeks ago was carving the Centrals attack on his way to 81 on Memorial Oval, was now starting to impose himself on the game and looked headed for a 30-plus possession game.
He found Toto Bodinner in space who unselfishly gave off to James Van Hoof who goaled and all of a sudden the Roos were out to a 21-point lead.
The Dees needed a spark and that came in the form of young Scotty Clark who drifted down from his wing to kick truly on the run.
The Dees had their first to bridge the gap back to 15 points. The Roos answered straight back with goals to Peter Usher and Damien Hennemann to give them a handy 22-point lead at the first change.
Roopena came out full of run after the break with Ryan Burgess pushing forward hitting Matt Oliver lace out.
He kicked truly and the Roos had the perfect start to the quarter, a lead of just on five goals and the alarm bells were starting to ring in the Demon camp.
Reigning Whyalla News medallist Ray McIntosh tried to lift the Dees, but he was playing a lone hand as the Roos ferocious attack on the ball and pressure on the Demon ball carriers was causing turn overs.
The Roo midfield prepared to run forward of the ball and their hard running was now starting to pay dividends with Peter Usher kicking a goal on the run from the boundary and when Damien Henneman took a strong grab and goaled, the lead was seven goals and the Demons looked all but shot.
Hennemann quiet easy could have kicked three or four for the quarter if not for some inaccurate kicking.
Ed Wilson, who always gives 100 per cent, was front and centre as he crumbed the ball and slotted through a goal to give the Demons a much needed goal and maybe some hope heading into the second half.
The Roos were all class in the first half and the second would be no different.
Oliver got them off to the perfect start as the Roos were now kicking into a three to four goal breeze, but you wouldn't have thought so with the amount of footy that was being pumped into their forward line.
Oliver kicked another before Ed Wilson kicked Souths fourth and only goal for the quarter to halt the Roo onslaught.
Ryan Burgess, who was having a day out, goaled just before the siren as the big bodied lady started to warm up her baritones as the Roos went into three-quarter time with a commanding 63-point lead.
The final quarter was a training drill as the Dees pretty much gave up the ghost as the likes of Feibig and Burgess moved the ball from one end to the other with ease as Roopena ran away with a convincing 86-point win to give new coach Waylon Nielsen the perfect start.
The Roo midfield lead by Ryan Burgess, Greg Fiebig and Peter Usher were outstanding winning countless clearances to give the likes of Matt Oliver (eight goals) and Damien Hennemann first look at the ball.
Toto Bodinner is like a good wine and was at his elusive best and Shaun Seely and Paul Zucker were solid down back.
Good players were hard to find for the Demons, Matt Perry was under barrage all day, but gave his all, Kendall Plant made a contest at centre half forward all day up against Matt Manfield and 50 gamer Steven Barford tried hard.
It will be a long fortnight for the Demons who come up against reigning premier North.
