I'm expecting it to be cool which will be nice for the clothing I intend to wear.
I'll hand out flyers in my neighborhood instructiing them to come with friends. That should do.
My husband bought a sport coat and I have a wool peacoat for if/when it gets cold. We're keeping them in the hotel room until we need them since we're at GCH. I'm pretty wimpy with cold, though, so I have a feeling I'll cave in early lol
