Cager? What does that mean exactly?

If you're referring to cars as cages, then my name is also included in that bunch - PatrickGSR94. It's been my internet user name everywhere ever since I bought a 1994 Acura Integra GS-R back in 2001, with 89K miles on it. Still driving it today with 315,000 miles on original engine and transmission, still averaging 31-32 mpg.

I bet most people with car-related user names also use them on other forums around the 'net including car forums, or started using it on car forums before joining BF (like me).
