I have a traffic circle (rotary, round-about) just down the road and sometimes when I'm coming home (slight downhill) I'll go shooting into the rotary (yes I look for cars) and do a couple laps just to get that lean at a good speed (usually about 24 mph at entry).

With light traffic, it's a blast... you should see the expressions on drivers faces as I pass them or stay even with them. Yee-hah!
