I don't see it on the Recreation myUMBC Group (yet), but attached is the January 2018 Rec Swim schedule I received from Josh Lightfoot (I think it was a broad distribution by bcc, which you may have received as well). As Josh notes, the schedule is a bit different, especially M, W & F mornings (8-11 a.m.), so check it out. I don't typically swim in the morning, but it seems like an improvement over the 7:45-9 a.m. and 10-11 a.m.combination.
Also, I'd hoped to be a little further along, but starting in January, Rec Swim guards will also be scanning ID cards, to help with data collection (see attached). Special thanks to Student Affairs IT Manager Ken Schreihofer and Assistant Swim Coach Elyse Gibson for getting this going.
