That may be an option. Are you planning on staying at the AVI Resort. If so, I know some seriously bitchen riding right outside the Resort area. You could ride for days and not get bored. That is a good idea. I went last year for four days and had a blast.
I met a guy out there last year from TT who gave me the tour and now I keep going back, only 240 miles for me...
Taking my son out there wkend of 12/10 and if the lady says we need to be out of town for the 25th then I have to do it, love that desert-hoping for rain. Indian fireworks and $50 beers.
