I checked out the link and the show is on Rain or Shine. Hopefully we get some sunshine but I'm going anyways. I checked the weather for Madison, CT and it said that there will be morning showers diminishing throughout the day, so it may get better as the day progresses.
Cellar, which way are you coming through manchester? If I know which highway you're coming in on, I can pick a place to meet. Let me know. I'll be checking in here over the course of the night.
