The Sanford garden club isn't a very large building, they did have a sale last fall, I didn't go but a friend did and said they only let in so many at a time, then as people came out, they let someone in, she said it wasn't that bad of a wait.
I'm not sure if they're going to do it that way this time or not, doesn't say it on the website, it did last time. I can say if you have to wait outside in a line, there is no covering from sun or rain.
Famous last words.
