Okay, so it sounds like I've got a guide for my next jaunt down that way....! I've only gone east to where it turns into the narrower single track (so in other words, the flat part!) and going west, I've just putz'd around the first few miles (crossed the creek and then a bit further) ... nothing that qualifies as a leg burner though! Our last house was right next to that new retirement home on Bear Valley so I'm very familiar with where those trails are... I didn't connect the mule hill name w/those trails because I was thinking "ROAD" not either/or

HOWEVER, when Jason shows up, I think you should have him do hill repeats on that hill that goes up to daley ranch

... or mt. murder, either one!
So, I will expect a guided tour (preferably west-bound, as I am not very coordinated!) when my mtn bike shows up!!!

Perhaps I can drag a few other peeps w/me!
didn't know you were a tour guide, did ya?
ps. thank you for the detailed info... I never realized what all was beyond the points at which I stopped!
