Ok, I getcha.
I was concerned about it coming across as "half-assed" or something, but it sounds like we have a chance to make a good impression.
I won't have much ready to sell by then, but I can try.
What time Friday? Also, I need to make sure I'm not the only one there. I've given tours to large groups before, and it's so much easier if we can break them up a bit.
Plus, it would be nice to have a stationed "greeter" to let people know that tours are being given (if everyone's out giving tours, someone walking in might be a little lost.)
