so what's your policy on long-distance 
pro-tips and idiot responses alike are welcome.
Ovary perspective: Terrible idea if further than four hours by car or you are completely loaded with both time and cash.
I once dated a jerk who lived six hours away. Dude cheated on me with some one-night stand in a bar, like IN THE ACTUAL bar, and didn't tell me about it until I had already driven all the way there and delivered the goods.
But I guess having a long-distance girlfriend worked out great for him except for all the wasted gas money and dates that lasted entire weekends instead of just one evening.
This is kind of turning into TMI, so I'll stop.
Short story -- terrible idea unless you really, really think you're going to take this one all the way to the finish line (altar.)
