FI still has to see it in person, so it isn't actually concrete yet, but it's definitely a win for me, so we'll call it a "wet-concrete" plan.
The location is this fantastic little museum in my home county. It's very small, but it has a lot of WWII artifacts and military history stuff. And for the low, low price of $175, I've been told I get to set up the day before, have the whole day of, and they'll set up and break down the chairs, plus every attendee gets admission into the museum.
The patio is the main plan right now. It's absolutely lovely, although it needs to be pressure washed once the trees quit having treesex.
The auditorium is the backup plan in case we get a shitty weather day. It's not as lovely, but it's a very neutral blank space with grey carpeting (none of The Carpet!) and could be very pretty. It's set up for a baby shower in the pic.
Sorry for the wasteful AW post but I'm so freaking excited. It's perfect.
