I have been throwing this delima around for a couple years now.  How do I keep TOT's from mobbing my poor mother passing out candy.

My yard haunt is not one you can walk through.  The front yard has a lawn area in front of the house and porch, then the driveway, then off to the side is a small lawn area that I also decorate.  My mom usually sits at the corner of the porch by the garage to hand out the candy.  With our numbers growing to hopfully over 400-500 this year, I can't think of a good way to keep the kids from bunching up.  We get large groups of kids coming up together and it is hard to keep track of the ones who try and double dip.  I have thought about putting up some lines that they have to go through one coming up to the candy and the other leaving.  The only thing is that people like to stand and look at everything I have in the yard and then things bunch up and I have mobbing again.

My latest idea is to have my garage open and block off most of it but have it so people can mingle and look on the driveway but to get the candy they have to enter in a single line into the front of the garage then back out to the driveway. 

What do you think?  I am open to any help anyone can give me.  PLEASE!!!!
