Dear All,
I have researched ultralight usage here in WY and at our high altitude
(6,500-8,000' in the dunes), the time when vital lift is favorable is
during occurrences of higher humidity like in the early morning and
evening. Then, there are days like yesterday when our winds here were
over 50 all day..plenty of lift!

I have a small airplane lined up to video tape areas to do future ground
searches. Air search benefit will be to identify concentrations of
parabolic dunes, and concentrations of playa lakes (especially near
roads) to cover on the ground.
With high wind possibilities and attaining lift in a rarefied
atmosphere, I have bypassed ultra lights here. Our local balloonists
here also comment on no control of speed or direction and by the time
they get out to the "good" areas, they are headed for the ground to shut
down, or are headed for Nebraska.
Balloons take a group to support them and don't carry many.
A motor bike, or a four wheeler would be more practicle...but don't rule
out the good old horse.
Ranchers and herders have used ultralights with some and not some
success here for 20 years. Maybe a helicopter is the answer....Yesterday
a large ski boat kite and a pickup truck would have worked.
Wax wings,
Dave F.
