That's a tall order for anyone from Flagstaff as its a 2.5 hour drive each way to Lee's Ferry and 4 hours each way to Pearce. That's 13 hours of driving and a lot of time for a little boat rental income.
I'm just off a GC trip and used my Antix 2.0. Good boat but lots of inadvertent stern squirts when big waves hit me. Next time I'd be in a boat with more stern volume like a Zen or Nirvana.
