I'm forgetting something.

So much to my chagrin, it appears that Orlando will be mired in the midst of a cold wave for the Goofy. The low for the half is bouncing around in the high 20s and the low for the full isn't much higher. It hasn't been this cold for a Disney race that I have run ever, but it does remind me a lot of the first one my wife ran about 10 years ago. She was a newbie, and I was just a spectator. I remember we ended up buying a sweatshirt just so she could wear the plastic bag to the start. That year, it was so cold that runners were hanging out in the exhaust from the generators powering the parking lot lights. We made the decision that a little warmth wasn't worth carbon monoxide poisoning.
I think we're a little bit wiser at this point, we're taking throw away clothes, space blankets and disposable tyvek coveralls to the start both days. We'll look odd at the start, but we won't be horribly cold. I'm actually going to check a bag with some warmer clothes in it for the first time ever, but its still going to be cold. At least I won't have to worry about an ice bath afterward. I'll be fine in a long sleeve shirt and shorts after we get going.
Packing is presenting an issue, though. I'm sure I'm forgetting something that I'll be kicking myself for on race morning. I just can't figure out what it is.
