That is indeed the plan for my girlfriend and myself. I talked it over with my friend, my girlfriend, and her parents. As of now, I will be taking zirkietricks to and from the meetup, and will be returning with Taucer as well. So my car is completely full. (Side note, Girlfriend and I may be heading down a day or two early to spend some time with her family in Maryland/Virginia, then run up to Philly to get zirkietricks.) That opens up two more spots at Dave's house, and our names can be removed from the "crashing at Dave's place" list...
Note: I'm currently in Indiana... Girlfriend's sister just got married, and I played Trumpet Voluntary for her walk-in. I'd show you the video, but I played horribly... I hope to never watch it.
