This morning had that rare perfect range of temperature where you can keep up a normal effort yet still arrive cool enough to go right to work. I get a kick out of days like this because you'll see bike riders wearing everything from shorts and jersey like me to sweaters and jackets. The "old guys" were out, a group that I see from time to time who like to holler "on your left" to each other as I pass, after I "dinged" them and bid them good morning. A pleasant, cheerful bunch who I used to think were just beginners warning each other, but they've been at it long enough that it's a group convention of some sort. The older cranky walker (another regular) was also out, standing in his lane staring up at the trees as is his sometimes habit - he gets quite upset if any bicycle passes by without acknowledging him so I usually ding at him as well. I wondered how he and "the old guys" interact with each other, but circling back to eavesdrop would have been too weird.
