Another idea is to change your password before the trip. Then, use that password to access your online banking. When you get back from the trip, change your password back. I've used many public places around Lexington, KY and have never had an issue of one of my accounts being hacked into.
Another idea is to download and install LogMeIn from
http://www.logmein.com . Then, when you're on the road, you can go to logmein.com and access your own desktop from any computer connected to the internet. I use it all the time, and it works great!
