A very nice ride in at 70 F ( 21 C). The humidity is down, so it was a perfect morning.
I have had bursts of tailwinds, but never steady. And yes they make you feel very strong going up a hill. I have an area of the ride where if I tilt my back to the right a little, I get a nice push up one of the hills. One of the little thrills you miss, if you drive a car.
