What's your opinion on dating someone who lives 2 hours away?

So I went on a date yesterday with someone who lives 2 hours away from me. We agreed to meet in the middle. He had a good time, had lunch and went bowling. If she lived a little closer, I definitely would give her a 2nd date if she wanted. But right now, I'm very conflicted. 2 hours away is quite a while, especially for someone I've only met once. I know some people do it, but they already knew their other pretty well. Plus, gas prices aren't helping much. What do you guys think?
