I've also done some HS baseball umpiring the past couple summers but I think I'm taking this summer off. Not bad money but like @1UNI2ISU said, parents yelling at you every play just gets old. 95% of coaches are great. 95% of parents are terrible (probably an exaggeration but you get the point)
I will be coaching tennis this spring and should have a kid that goes pretty far at state so that'll be fun
If you want to do some little league this summer, let me know. A little more laid back than HS.
Softball is much easier than baseball as well. I can do games solo for 10 year olds and be done in 70 minutes.
