A hundred miles is less that two hours, most of the time. I go farther than that to go to my dentist. (No lie, my wife goes even farther, more like 6 hours, even though we have the same dentist, long boring story.)
Some people can, some people can't. Personally, for something like this, I might go 100 miles. My point is more that it's lame for people to say they can't do it (without a truly valid excuse) if they live 5 to 20 miles away.
