Hi Michael and sorry for the delay in replying. Got sidetracked with the untimely passing of a hang gliding friend. Mingus is a big air site and we love it. May and June are probably the best months, if you are planning to come out. July through September can be good, but moisture from our Arizona Monsoons frequently causes overdevelopment in the afternoon, and altitudes reached are not was high. If you do come out I would be glad to sponsor you there and get you oriented with the site and LZs.
