Tim, sorry to hear you're heading back to Arizona, but I can't blame you much (it's officially cold here now). Hopefully we'll see you a time or two next year.
Sounds like it's time for some indoor tire's for the 1/10 buggy... there is also an indoor track in sharonville now, though I don't think they're officially racing anything yet. Just open practices twice a week. Haven't had a chance to see it yet.
