I had a great flight on the 19th of December, 2021.
Here's a recap of the flight with in-flight photos:
I took a 4000' tow. The headwinds on the flight computer showed 340 at 11. We released between Signal Knob and the Strasburg quarry (1728Z). I circled around in some weak thermals. Nothing really usable over Signal Knob or Meneka Peak (1740Z). The computer said the winds were too northerly for me to go run the ridge (See my diagram below, which I've drawn from experience, anecdote and survivorship bias; the numbers on Sunday were between "Marginal" and "My Limit" ). Eventually I found a good thermal right over the fish pond (1751Z). I worked my way upwind to the next band of clouds (1800Z). Riding just below the clouds, I gained speed, popped out in front of the cloud and got into the wave (1803Z).
