Neighborhood Root Beer Float Party

Recently I've been extremely disappointed with the fact that we don't know any of our neighbors very well. I wish I could say that we've only lived in our condo for a couple of months and are still getting settled; however, this August marks the 2 year mark for us and I still have a hard time remembering anyone's names.
In light of this we are hosting a neighborhood root beer float party. We'll pass out invitations this coming weekend and pray that people actually join us for our party. Above you'll find the invite I put together - I think it's pretty cute!! (thanks Sharla for help with the rhyme)
So - wish us well! It's sure to be quite awkward conversations but will hopefully prove to be a time to meet new friends. Anyone have any other idea's of ways we can serve our neighbors?
