I'm taking a 1-2 month road trip around the US and I'm planning to put updates on my site every day with photos and such. Obviously I can dial up from hotels, in most cases, but I'm wondering if I should invest in a wireless card. Do most of the Starbucks around the country have wireless access now? It seems I might be able to get a faster connection through wi-fi than at a hotel, and I'd rather hang out somewhere social anyway.

Any experience/advice with this?
