"A buddy of mine, a dog lover and travel writer, asked if I was going to include Summit Lake in this guidebook. I hadn’t thought about it, since I really don’t often get to this part of the state on my jaunts with the dogs. “Oh, you have to include Summit Lake,” he said. “I don’t know of any dog from San Francisco or Sacramento that hasn’t used this trail.” So I did a little research, and found that the trail is canine-approved by www.dogfriendly.com, a website that provides city and travel guides for people and their pets. Next thing was to take a trip out I-80 to Donner Summit and the Summit Lake Trail. OK, it’s not much of a trail for some people, but it is a scenic trip that can be done—out-and-back—in just a couple of hours. And even in late fall, when the weather was crisp and there was the threat of snow in the air, carloads of people were streaming off I-80 to stretch their legs and let their dogs stretch too."
