Hi Noel,
Montague will host a regionals along with standard and open nats (6/16 -
6/25), probably the first 5 days. The regionals may be just sports.
Montague is/can be quite technical, but there are airports about every 20
miles or so.

Air Sailing will host their annual all sports contest in mid to late July
and it is quite low-key, but competitive. Usually very good soaring with
airports about every 20 miles or so. Camp on the field or drive to Sparks
which is 30 miles. Could even drive to your Truckee house, about an hour
away. I will mentor you at either one of the above contests as long as you
remain below me on the score sheet........................start beating me
and your on your own!
