We have a little tradition going on Thanksgiving. We ride up Lower Big T to Angeles Forest , over to Angeles Crest, and down for a guarenteed hunger inducing ride that will help ease the guilt that's sure to come later after dinner. Some ride from home so we usually meet at the Jack in Box at Oro Vista and Foothill in Tujunga at 9am. The LakeView Terrace Rec center on Foothill is a good place to start closer to Tujunga. I think it's a little over 3000ft from the Oro Vista. to AC. Another option would be to ride on up to Newcombs and have Turkey up there. I've heard they put on a pretty good spread.
