Dave, I recommend pitting once every lap if you want to finish the race!
Phil and Robert, thanks for your comments! It's my pleasure to add unique things to this addicting game.
Chadley, yeah there's a lot of work to do before any scenery goes up. I just went hiking with my girlfriend in the Bad Lands for the first time during fourth-of-July-weekend, and as soon as I got home I did a few laps on all your South Dakota tracks. Now that I've been over there I can really see how great your tracks are! Thanks for the great work!
