hahah, I cross that median for lunch daily.
I'm here, dunno about interesting rides, I got my bike about 11 days ago, and I've got a lot more weight to burn. Gained way too much after Katrina, but I've put in about 70 miles since I bought the bike, and I enjoy the hell out of it.
I'd recommend that you call an LBS and ask them about the good rides. I've been riding near my house since I have no rack on which to transport the bike, but I know a lot of folks ride in City Park.
