Your comment about the heat could also be applicable to Houston and my rugby post. The rugby schedules are similar to MLB in that the northern teams NY, Boston, Toronto and D.C. usually head south and west early then NOLA, Atl, Houston etc play up there to finish out the schedule. Even so, gotta be brutal for those boys as they’ll still be playing even a couple games when it’s 100.
Regarding your post about last year at the Aussie open and their Extreme heat policy, Houston P.D. has something similar. When the heat index hits 105, cops don’t have to comply with the mandatory policy and can choose to not wear their vests.
