Elephant Hill is awesome, but last time you guys did it in a large group you were only able to do the main loop in time. It is a crime to go there without hiking the Joint trail and/or Confluence overlook.

I like Gold Bar Rim a lot, but the prospect of getting 20+ vehicles down and back up that big wall in less than 8 hours is daunting.

Top of the World would be nice if it isn't snowing like last time...

Fins 'n Things is a good overall choice, and intro to Moab wheeling for the noobs.
