I've been there twice now. Did you know Mile High Pizza doesn't open until 4pm on weekdays? They'll get no business from me! The Mini-Mart has the best deal on soft drinks--a 44-oz Coke for only $1.29 + tax! (I think their bananas go for 29 cents.) Or did you know that the local bike rider could down 5 ClifBars and 2 tacos, and still be hungry for a McD's meal before dinner? Or that he could down an apple fritter, a cake donut, a pastry, and an oatmeal cookie on top of several ClifBars in a day besides breakfast and (very large) dinner? Now you do.
My first route to Wrightwood (July 31), where I used nearly all of the highway, is 91 miles one way. (Dad picked me up at La Cañada Flintridge on the way back.) The route I took the second time (Aug 13), which took me up hwy 39 (San Gabriel Canyon Rd) to Angeles Crest, was only about 65 mi each way.
A man posted about his own ride on hwy 2, from Glendale to Wrightwood.
