Thanks for all the replies--a lot of good ideas. We were able to find a Best Buy store today and found both a charger and battery a lot cheaper than I imagined. Those would be good candidates to leave in the car. But I also think packing my small point & shoot is so important. It was quite difficult to use my phone when we were horseback riding yesterday and I wouldn't have wanted the 60D. I am still migrating from my film SLR to DSLR and finding it a lot more than Ianticipated.

This is a good idea that I had not thought of. I have a variety of other small electronic connectors in the car--why not the camera?

I should be able to get my charger in San Diego. It's just between now and then.

Looking for a little advice. Currently, in Rocky Mountain National Park, Heading through Utah Canyon lands to San Diego with my Canon 60D with 1/2 battery charge. Was excited about the prospects along the way, but my forgetfulness left the charger at home. Will be able to have shipped to San Diego, but will miss Utah Parks. Would it be better to rely on cell phone camera or try to find a point and shoot, like the Nikon CoolPix which uses easily replaceable batteries?
