Who are those people that Cause traffic at intersections?

I have been annoyed at people that are in the middle of 4 way stop sign intersections asking for donations. Instead of being on the side of intersections like this picture, they are really right in the middle of the road inbetween the 2 lanes. Today they were at 2 different intersections, one in Loganville and one in Winder. What is annoying to me was that these people cause a longer backup in traffic at those intersections. Also it has to be pretty dangerous to be in the middle of the road. I asked my mom today who she thinks these people are and she thinks that they are Shriners. I looked them up today at http://www.shrinershq.org/Shrine/Default.asp. Interesting enough they are Master Masons. It sounds like they are trying to get donations for Shriners Hospital. Shriners Hospital sounds like a great Hospital that helps children get medical help without the family paying anything. I am a little curious if they take all the money people donate and give it to the Hospital or if they use it for other things like the Temples they have, or their social activities, etc, or if they might take some of the donations for themselves. Overall it sounds like a good thing to donate to.
