Ha! I swear people drive by me thinking I'm having a convulsion or something! I'm usually 'jammin' out like a teenage girl!
Totally all the time. But now that I'm a public transit girl I have to limit my jamming so I don't get mistaken for a flash mob.
I so totally do, though I get some funny looks most of the times! I just smile, wave and drive off I just can't contain it!
