Last flight at Boulder

The Day started with moderate amount of Cu's, but they looked broken hinting strong west wind. I waited late afternoon to see if they overdevelop, and they didn't, so I launched around 2pm. After releasing at 10,000 ft, I crawled under a few clouds only to find marginal lift. Also, the wind was 15 kts from east, which prevented me to go further west towards mountain. I went up to 11,000 to 12,000 ft a few times, but couldn't go above it. It appeared that there was a wind shear there, and the lift was chopped. After scratching a couple of hours, I ended rather crappy my last flight at Boulder.
