[BBTC Ride_calendar] Car Rack on Hitch

I am looking to get a new/used car rack that hooks to the velical by the
hitch. I have looked at www.amazon.com www.bikenashbar.com and
www.performancebike.com they all have some nice ones. I am hoping to find
one that can look atleast one bike to it, the outside one, so when I am in
the store I don't have to worry about the bikes running off. Does anyone
know were I can get one with a lock for atleast one bike?
