Isn't that the truth. What I learned from touring all over the US is that each area is different in the way they react to your music. In San Francisco people would get on the dance floor and dance, but in Los Angelos, it was not cool to dance when seeing a band. The only way we knew they liked us is they would actually look at you and nod their head. That is LA speak for I like your band.
To each their own I suppose. We had fans that followed us on the road and in some venues they would be the only people dancing. Some cities just don't dance to live bands. Sad but true.
