I our area, indoor FP softball game fees are $30. You work solo and games are 75 minutes each. Usually work a double header on a Saturday as 4 games are generally scheduled (sometimes 5). We also have an artifical surface for the playing field. Lines, batters boxes and plate are painted, regular bases are placed and there are lines on the outfield wall indicating double, triple or home run of course when the ball is hit on the fly above any painted line. There is also netting above the fence which also covers the entire playing field. Any ball hit off the netting, in fair territory, is live and if caught is an out.
I am certain to wear full gear with the exception of not needing a ball bag and plate brush. And as CLBuffalo mentioned, pitches and/or foul balls that hit the playing surface deflect very fast and can find "unprotected" body parts. Matter of fact, last season we had a HS sophmore catcher take a foul ball to her crotch area. Time was called and the athlete humerously said she wished they made female protection for that area. I told her and her coach, who was with her during the time out, to check Honig's web site as female protection is available. They both seemed suprised and said they would "check it out".
The indoor game is unique compaired to "regular" FP softball but IMO it helps keep athletes and umpires "in tune" during the off season.
