Last weekend- the only weekend that I haven't umpired a tournament this season- we had temps in the mid-to-upper 90's and high humidity. Two umpires went down in the heat, requiring visits from paramedics. Part of the treatment was to lie the guys down and pack ice around their bodies.
One of the guys that went down was our district ASA commissioner. The only reason he was umpiring at all was as an emergency replacement for the first umpire that went down in the heat! When he told me about this, I said, "Gee, I miss all the fun stuff".
Instead of roasting on the field that weekend, I was basking on the beach in North Carolina.
