Tulip, it's doable and I'd do it with you. There's enough civilization stops along the way,that you don't have to bring too much water and/or food.

The group I'm going with is a group that has basically been doing that - but they've broken it up into 1 weekend trip a month to make the logistics easier for everyone taking off work. I think this is their third stage - I can't remember what i was doing the last 2 months, but I think they were weekends I already had plans that I couldn't change.
