Haven't worked HS in a few years, but as far as college the closest for me is about 30 minutes (in rush hour traffic) and the farthest I go as a general rule is about 4-1/2 hours or so one way. It's not all that frequent, but when a supervisor calls and asks if I can help him out ... the only answer I give is yes (presuming I'm open that night).

I run a pair of mid-sized manufacturing facilities and leaving when I need to isn't a problem. I often go straight back to the office after a game and work for a few hours, plus I work the phone quite a bit driving and pull over when necessary to read/send emails.

In Central Oregon we only have 16 schools. 5 minutes to the closest, 3 hours to the farthest for hs. Juco is 3-5 hours.
