Kind of too late I think although the hottest portion of summer is historically ahead of us. I met 2 friends for dinner last Tuesday. I usually walk but after I parked my car in my secret free spot, I started walking and realized it was really dumb to try 3 miles with the temperature over 100 and the sun still blazing. So the Green Line was right there at Coolidge Corner and thankfully the ac was working. I decided to get off at Kenmore and walk the half mile to the restaurant. I noticed there wasn't anyone older than 4 decades younger than me on the street. I walk 5-8 miles every day and I felt the half mile walk. As soon as I walked into the restaurant someone handed me a cold glass of water and a seat at the bar. I walked back to Kenmore after dinner and took the Green Line back to Coolidge Corner and then drove home. I still went out to walk a few miles close to midnight with my wife. Temperatures were still mid 80s even in my hilly leafy neighborhood. Last week was close to as crazy hot as it can get around here.
