So there is no confusion....this is not a party or a get together of any kind. It will be in a public place and the idea of anything wrong with one person dropping off a bag of toys or basket balls or gift cards to another or it being something that anyone would even think was unusual this time of year is not an issue we have ever dealt with.
This is the 5th year and there have been 100s of drop offs over those years in dozens of places with about 12 so far this year. Most people drop by and drop of their stuff and head back to work or home.
I know the story you refer to well. I had a few good friends involved in that incident and it was nothing remotely similar to what we are doing here. What happened there would never have occurred were it not for a handful of people with problems not related to even the hobby.
