From Julian, thanks for sharing and have fun!
We flew to the Grabs Canyon today. By the time we arrived by 10 seater plane, the thermals were quite vigorous and after our helicopter descent 4000 feet to the Canyon floor, it was booming. I would guess cloudbase was at least 20k and a great convergence set up later in the day, complete with CB's and lightening
Cheers from Sin City
