Perhaps someone can organize and lead a run up Rattlesnake Canyon? That one is always fun this time of year. You get to start out in the warm sandy desert and end up in the butt-freezing snow. That weekend of Feb 6 might be a good one, since many people may be busy the following weekend.
I'm not available for much more than short San Diego area day trips for a while. I'll try to set up an Anza Borrego run here soon, but it won't be challenging, only scenic. Someone else will need to take the lead for the challenging stuff.
