This is just my observation, but it would appear that "we" have allowed the line dancers to take over the squares and the chairs. Beginners on one side, plus on another and intermediates on another; and if Scooter is playing then you will not find a chair all night.
When we first bought and moved here the squares were open and space was available to all types of dancers, you would see some really good dancers (ballroom), but now it would appear that the squares are filled with mostly line dancers - of which I am one - however, I do not dance at the squares, I choose to dance elsewhere.
I came through LSL last night at about 6:30pm and it was so cold and windy that you had to be an eskimo to be out there last night!
