Last time i was there (03 for the 20th) seems like most days folks met up/staged at the City Market parking lot (City Market = a supermarket chain in the region, like Shaws in the NE or Lowes in the SE)
I saved my 'value card' and actually found it again last night (no, I didn't keep it on my keychain for five years) so if I can remember to bring it to Moab this time I'm all set for the deals of the day.
City Market had great pre-made sammiches and hot coffee BTW. Hope that still holds true.
