California Demo Days – April 30th to May 2nd. Make sure you
register by April 12th to secure your free ticket to the Saturday night party.
If you only have time for one get-away in 2015, this is it.

This is the Wills Wing Demo days to end all previous Demo Days,
located near the large population of hang glider pilots. This is a huge
undertaking on Wills Wing's part. Be a part of history.

Steve Pearson updates:

You can still register for a dinner ticket until April 26th but
you pay for your own meal ($20). Wills Wing is paying for all those who
registered by April 12th. Register at
https://www.willswing.com/crestline-soaring-society-demo-days-registration/

We'll have a very limited number of tickets onsite until they sell out.
