I think there are a good number. I'm one! (waves!!) Some of our regular posters are SUPER local to the parks -- great sources of info there. Once you start cruising the boards regularly, you'll start recoginizing the names of our local DISers. Welcome back to SoCal! Glad you're already posting. Looking forward to having you join our band-of-locals once you're all settled back in.
ETA: I'm going to move this to the Disneyland Community board where I think you'll get more responses.
You're one of the locals I was thinking of! Sometimes threads on this board get quite a few responses. We'll just have to send the DISers we know are local over to this thread.
Scrolling through the Disneyland Community Board for EXCACTLY this question... I know it's been a few months but just wanted to chime in as another local! I'm 20-45 minutes away, depending on traffic and DH like to go often we're early 20s and a lot of friends don't have passes, or don't have the same level passes so we find ourselves wishing for more "Disney" friends to go with. I would agree with pp, I feel the Disneyland board doesn't get the love I wish it did :/
