Went to the Rose Bowl Comcs & Collectibles Show at the Rose Bowl in Pasadena, CA. It is located inside the Rose Bowl grounds and is part of the large Rose Bowl Flea Market event, so you will have to pay the $8.00 admission fee to get in; the parking is free but be prepared for the crowds.
The actual Comics area is located right in the main entrance area to the left and is situated under the Rose Bowl area along an underground passage way in a room location unlike the rest of the flea market. The rooms is roughly the size of a class room and had about 15-20 vendor tables mainly selling comics and toys. A good majority though were toys that were modern and comics for $1.00. I popped in to check it out and didn't see anything that was that different than what you could see at the Frank & Sons Collectibles show in the City of Industry.
I did pick up four 25 cent comics to help fill in some gaps in my run. Several of the dealers had Silver Age and Copper age books for sale and some 50% off TPB (but none that was of interest to me). The event is pretty sparse so I don't recommend going to the Flea Market just to attend the show but more like a side-trip if you decide to check out the entire Rose Bowl market which is huge. It was pretty hot today so be prepared with drinks or you'll be paying $5.00 for a lemonade slushie from vendors there. Found a few vendors in the main market area with comics varying in ages, but were priced way above what they should go for, for example 90s glut comics for $1.00 which wasn't even worth it for haggling.
