I am going with few expectations since I don't know much about the Fest other than there will be familiar faces (like Queen's Gambit, if I understood rowangolightly's post correctly) and it's a 'tent' festival. I imagine it might be much like Jeff City (which I attended as cast last year).
But what to wear? A friend who is cast suggested I come as a Spanish lady, but that costume is going to be HOT. (but SOOOO tempting, just the same). My friend isn't likely to be in garb, though. I could wear my lighter weight 'garb' but it's just not really period and I find I'm becoming a snob about such things. :O But the only other alternative is street clothes and that's just not going to do it! Oh, the indecision!
Edit: what fun - those Calvin faces are perfect for what I am feeling right now. LOL
