Even though the ride was in mid-August, the air temperature was in the upper 40's at 8:00 a.m. There was medium thick fog also for about the first hour. Then a 40+ degree change in air temperature by the hottest part of the day. By afternoon the temperature peaked in the upper 80's in the valley, but was in the mid 70's in Burke's Garden. It was a great day. A very scenic ride with friendly staff and riders. Lots of farm land with cattle grazing. The school and nearby farmland near SAG 2 I was told was used in the production of a Lassie movie filmed the late 1980's (?). Be prepared for long hill climbs. Some of those will have some steep sections, though the steep parts are short. The climb back into the bowl of Burke's Garden is especially long. The traffic on routes 19/460 and on 61 was light in the morning. In the afternoon traffic picked up on both roads, more so on 61, though neither was heavy. The traffic on both loop sections was very low. I'm guessing there were about 50 riders on the two longer rides combined.
