I didn't know until recently that Harrisburg had the Pennsylvania National Fire Museum. For $5 we get a 1.5-2 hour guided tour around the museum and cameras are welcome. Our tour starts at 11am but i'd like to get there by around 10:45 so that we can be organized before we go in.
After the tour, we can go to lunch at a nearby restaurant - I'll make a reservation closer to the date. Lunch will be around 1pm for those who need to plan accordingly. You will be asked when you RSVP whether or not you are interested in lunch so that I can get an idea of how big of a space we will be needing.
