Re: Los Ageles, Red, Blue,gold & Green lines.
Hi:
I am a Director-at-Large for Southern California Transit Advocates - [
www.socata.net] - and one of our members-officers, Charles Hobbs, posted on our member board in reply to my posting your question, the following:
"I've never had any problem on the MTA lines. I'm very discreet though (small camera, no tripod, no flash in the subway, don't try to hang around too long or enter non-public areas, etc.)"
I hope this is of some help.
