Greetings. I am a new member to this forum but an old somewhat experienced Jeeper / Wheeler. I have been to the Con. It is unbelievable wheeling and the scenery second to none. For those who have been to Moab it is a completely different wheeling experience. You have to camp to get full benefit so there is much stuff you need to carry in your rig other than your usual trail gear. I had to take the front seat out of my TJ just to get everything to fit. Regardless, it is well worth the drive. Like Moab, an experience you will never forget.
With all that said, keep in mind you will be at about 8000 ft or more so it is cool. It is possible snow will still be on the ground through mid July! That may make some of the trail impassable secondary to swift water. In addition, late July and early August the place is crawling with Jeep Safari and other big events clogging up the trail. We went in early September. The weather was awesome and trail generally clear of traffice and high water.
I certainly would be interested in taking another trip but cannot commit until dates are set.
