I don't like seeing the loiterers either but I am totally against stifling peripheral interest.
At this point in time peripheral interest is the only thing growing the program, I promise you it's not going 6-6 although that doesn't hurt.
Now if someone say the program isn't growing I beg to differ, at the turn of the century 9,000 on a clear day was seen. 12,000 on a rainy, option laden day is growth and future growth can be seen through the peripheral interest.
Don't kill it.
