After I discovered a perpetual ramming machine (by PERHAPS getting stuck in Connor's Squid), that was loads of fun. Jace died once or twice while showing us around. The gap got really annoying. I would have won the first race if I hadn't crashed in it, but I won the second one by going through it at full throttle. Guns are essentially useless, since you want to be moonshining 95% of the time. A crew with real players would change that.
Anyways, that was just too amazing. I'd love to do it again in the future.
