(Cassini is right but I'm sure you've already decided on a costume you can tell us about bloonuggets?)
I actually have local friends this year (gasp!) so I'll actually have a reason to dress up.
However I have not decided yet what to wear, I do have a number of choices. I recently unearthed a cow costume I made a long time ago that still fits (I had worn a halo and angel wings with it and was a "holy cow") that I could wear. Or I could be Gaz again. Or NeitherSparky. Or a medieval person. I was thinking of just wearing as much halloweeny themed stuff as I could at once and being a Tacky Monster or something.
