We were speaking about this idea in the all chat, and many players agreed that it would be a nice idea:
Doing bike races in route 17, for 4-5 players, with one judge that say "3, 2,1, go!" and another judge in fuchsia city that could see the winner.
In the end the winner would get the prize money, stored by one judge (or both)
And these races should be only at night :D
It would be a funny minigame for me and would get super viral
