That is what I do, I carry one that uses something called MultiSystem, it lets me boot a whole bunch of them, then when I am showing off Linux distros I boot several, and let people get an idea of what they are.
There are a whole lot of options for booting from a jump drive, I have not used a DVD now in years, I run into machines that do not have a DVD drive on them, and I do not carry a DVD drive around with me all of the time, so the jump drive is the way to go.
