I'm pretty sure this is top of the lift actually achieved by gliders
in the air. 3300 ft AGL is probably workable for many eastern sites
and possibly Hobbs but I would hesitate to start a task in Arizona
this low. *Contestants are likely to be soon on the ground at local
strips or eating cactus! *I personally would recommend a minimum of
5,000 ft AGL here.

just because the task is open doesn't mean you have to start, right?
