Here's a flyin calendar with my recommendations on places to go to see antique airplanes.  This list is weighted towards the west coast and towards aircraft type flyins for the types that I'm interested in.

There are lots of local flyins not listed here where you can also spot some great planes and have a lot of fun with the folks who fly them.  See below for suggestions on how to find them.

Other places to find out about flyins:

• Your local airport bulletin board
• http://www.flyins.com has a searchable database and email notification service.
• Various type clubs keep an event list, including the EAA and VAA.
• The event listings in GA News and Flyer, Southern Aviator, and Pacific Flyer tabloids.
