It's hard to believe but, coming from someone whose a bit burned out on "Moab", I still recomend going to see the insanity of EJS. It's been since 01 since I've been to a Safari, but waaaay back then... It was reasonable to get in plenty of good wheeling if you timed it right and looked at the EJS newspapers for the skinny on what big group will be where and when. IF you get up with the chickens and hit trailheads just as the sun is coming up, you will most likely have only a few hardcores out with you.
But if you party and sleep in only to hit trails at 9-10-11 am you will be met with crowds,lines and morons.

I've done close to 20 Moab trips since 1988 95% of which were in May and October/November and with a group of 4-10 rigs. I thought those were just as fun as Safari's or moreso.

Safari is worth doing at least once, just hanging out at Dump Bump or Potato Salad hill (late afternoons on a warm day)are worth the drive. (Not short wheelbase friendly)
