The length of travel
I just got assigned a USL2 line for a game that is 3.5 hours away in about a month from my National Assignor. It's not the money that does it (really!) it's just.. the time. That's practically a whole day. Especially when kickoff is 7PM.
What's the most you've travel (either 1 way or both) for one (or more) game? Is it a common occurance the higher up you go?
