Just an idea. Some people (like me) don't know all the shorthand words used in "biking circles", and it might be helpful to have a sort of dictionary for these things. So far, I've figured out: Squid - rider without proper riding gear (only helmet) ATTGATT - "All The Gear All The Time" SMIDSY - "Sorry Mate I Didn't See You" No idea what "OP" means, and I see it in many threads. Also, since I'm from NSW, I got no idea what "TAC" means. I gather it's some sort of Victorian thingamabob, and it's related to insurance? Maybe those could be helpful too.
