We were at a concert this past summer and the guy running the stage lights got mad when I whistled. I was dumbfounded when he told me I couldn't whistle. At a concert. Outdoors. I have seen several great bands here but the people in general are rude and not very friendly. I had my Michael Kors purse with me and lady at the gate said I couldn't bring it in. We were not parked close at all. The lady said to walk back and put it in my vehicle or I could "stuff it under a bush." Needless to say, I will not go back. Ever.
