You know, I sure could have used a charging dock at Frys a few weeks ago. My wife and I were at the San Jose Brokaw Rd. Frys, which is only 25 miles from our house, but we'd been driving around a bit before we got there. I wasn't worried about getting home, but I was looking for a particular computer and they were out of stock. The salesman looked it up, and said they had some at the Fremont store, which, he said, was, "what, maybe five miles from here." Well, that was five miles the wrong direction for me, but I figured it would still be doable. I remembered seeing that store from 680, but didn't remember which exit. So I took Montague from 880 to 680 and started north.
Five miles, ha! I'd gone 11 miles when I hit Mission Blvd, and still no Frys. That, I decided, was the limit of my range, and I turned around. It turns out I only had another mile to go, and even 120v charging while in the store would have gotten me back into my comfort zone.
Yeah, yeah, I know. That's what the nav unit is for, but I don't got no truck with them new-fangled thangs.
