"The skies will be turning purple soon," our bus driver Terry declared as the Freo Express moved to within 200km of Melbourne.
An hour later, drops of rain fell from the purple-grey sky as delirious passengers started singing "Fre-man-tle" to the tune of AC/DC's TNT.
We were finally in Victoria - and boy, were we happy.
After more than 3400km, 45 hours and more roadhouse meals than one cares to remember, there was a joyful - albeit exhausted - mood as the Freo Express coaches made their way towards the home of football.
Earlier we woke at sunrise to discover Adelaide outside and the shrubby, flat Nullarbor had given way to lush, rolling green hills.
The change in scenery gave weary passengers the sense we were on the home stretch, so they burst into Dockers chants once we crossed into Victoria.
The Freo faithful were quick to make their presence felt, with one climbing the "Welcome to Victoria" sign to hoist a Dockers flag.
Although some motorists were quick to remind us we were in enemy territory, it was reassuring to see WA numberplates honking and waving, purple flags streaming from windows.
Just before 6pm yesterday, the buses cruised into Southern Cross Station to great cheers from those aboard.
"My feet are swollen and we're tired, but it was worth it, it was a great experience," supporter Pam Hawkesford said. "Now we just have to hope we get the right result."
A Fremantle member for 16 years, Ms Hawkesford came over with husband Ted, who lives a double life as both a West Coast Eagles member and a Dockers member.
The 90 passengers started as strangers but after almost two days together they became friends and will meet today for the grand final players parade and again tomorrow to march to the MCG from Federation Square.
And though many longed for a shower and a bed, none seemed to regret taking the long way to "the G" and their enthusiasm for the big day was as strong as ever.
Some, like Harrisdale woman Sue Ditchburn, signed up for the return journey alone without even having tickets to the big game.
She and her father are both diehard fans and planned to go to the grand final together, but sadly he died in May. "I'm doing it for Dad," Ms Ditchburn said. "He was a supporter from the start.
"I missed out on the ballot and tried everything to get tickets - eBay, Gumtree, the AFL. But if it doesn't happen I'll watch it at Federation Square. I couldn't miss it."
So while the purple haze will be in the minority against Victorian fans tom-orrow, it is this kind of passion that will ensure the Dockers diehards are seen and heard all over town.
Melbourne, be prepared for the purple reign.
