Not physically-- mentally. Just got back from three days at Mammoth Lakes, and it is a place that I, even as a native Californian, couldn't really wrap my mind around riding-wise. The town is probably the most bike-friendly place I've personally ridden-- Class 1 paths everywhere. The Lakes Basin Bike Path passes 6 lakes in five miles, and the Town Loop is an awesome ~5 miles through the meadows at the east end of town. The roads (almost all) have nice wide shoulders, and even though there are literally hundreds of downhill mountain bikers everywhere, they are just magnificent roads to ride on. But now I'm home, back in the Inland Empire, and nothing is pretty. I think I might have been ruined. I mean, if you lived where I live, and then saw what I've seen, you'd be having troubles too. I miss it already.
Sunrise from the Lakes Basin Bike Path, just east of Twin Lakes
Facing west about an hour after sunrise, taken the following day from the above pic, about 250m east
Looking south across Lake Mary, 8910ft
Looking east from the Lakes Basin Path, down Mammoth Creek toward Twin Lakes
West over Lake Mamie, 8900ft
Looking southwest across Horseshoe Lake, 8955ft. Though in mid summer, it's more of a puddle.
The mule deer... they are not afraid. One of about a dozen I encountered over the 3 days.
