[St. Louis Blue]

I carry my indicator on the bases. I often work with less than experienced umps and often need to keep track of the count and outs for the time when the inevitable question comes up. Also, at my age, it isn't always possible to remember how many outs there are when the last one may have occurred 20 minutes ago.
I only wear my ball bag in the field when we work on one of our fields which has a creek running behind it. I carry extra balls in my bag and hopefully, between the PU and I we will have enough to get through the game. I also wear the bag when the fields are wet so I can carry a towel to dry off the balls as they come in from the outfield.
