Seacoast MA/NH/ME. Yesterday was 90degF with high humidity. I added 2 mi to my return trip commute for total commuting mileage of 30mi.
Felt great. I stopped for an iced coffee on the return trip, which really hit the spot, sat outside in the weather rather than inside in the air conditioning.
Otherwise, whenever I'm tempted to curse the heat/humidity, I flash back to this past Winter and tell myself to STFU and enjoy the heat.
