As part of SOPH we do work rotation on the grounds with different groups.  I am with turf & grounds, and so far have spent 8 days doing hedges and 1 day weeding.  On top of that, we also have classes, so on Tuesday I had a 4 hour class that ran until 8:30 and Wednesday had a 2 hour class that went until 8:15.  And, all of this has been in one of the warmest summers on record.  According to Accuweather.com (every good gardener seems to live and die by their weather forecast), the temps for this rotation have been:  94, 83, 79, 87, 93, 92, 89, 93, 90.  Be sure to drink lots of water!
