September 30, 2017, 7:00 AM–11:30 AM: TRW swap meet
This is a recurring event: Last Saturday, of every month
The TRW swap meet began in the 1960's and evolved into its current monthy schedule. It's always held on the last Sautrday of the month, regardless of weather, and regardless of whether it's a holiday. You'll find plenty of computer gear there as well as amateur radio equipment.
Starting time is 7 a.m. The swap meet closes promptly at 11:30 a.m.
The location is in the Northrop Grumman parking lot at the corner of Aviation Blvd and Marine Ave in Redondo Beach, California.
