Given what I saw last year in Rattlesnake Canyon, and the snow we hit in Big Bear once we got to the top, I would not recommend this run for a 4x2.DanielD said:
That said, we did have a Yota 2wd truck along last year, but he spent most of the day strapped to the back of a 4x4. The beginning part of Rattlesnake is a soft sand wash, he had to be strapped 2 or 3 times. Once we got up into the wet rocky creek bed it was decided to pretty much just leave the strap on and they basically pulled him all the way up the mountain.
There was a point where the group split, with some of us taking a side trail that has a section rated difficult in the Wells guidebook. You would not have wanted to be there in 2wd. 2 of us did that section in stock 05's, (4wd) but is was somewhat stressful. I should stress, though, that this was an "optional" route, a good portion of the group stayed on a relatively easy trail. If you look at the guidebooks you can see that most of the tough spots will be down towards the bottom and heading up the creekbed, the trails up closer to Big Bear are pretty easy and, at least last year, were well graded. There was some snow, though, and coming down the hill one of the highways was actually closed.
If you really want to go, and are very confident in your driving abilities, you may want to bring this up in the club thread on XOC and see if anyone else has a different opinion. You may also want to look at last year's picture thread on XOC, I think it was started by Xtoolbox and titled "Highs and Lows". Look back around Feb or March.
Not trying to discourage you from participating, but I would not want your first run with the club to be not fun. PM me if you want to talk more about this.
We should get a 2wd friendly So Cal run going sometime soon. There are lots of places that are fun and accessible. Last weeks run to Santiago Peak was doable in 2wd, and I know Fish Creek in Anza Borrego is passable (except maybe for the recent rockslide). Blair Valley to the pictographs hiking trail may also be a good one.
