I plan to go out. I make PJs for family and some friends for Christmas every year, and I'm almost out of my stock. (Though I don't need it for this Christmas, but I prefer to have it on hand to make in advance rather than rush in December!) I've never had trouble at previous BF sales - just the usual rush of people and long lines - but we moved to a much more urban area, so I'm not sure how bad it will be here. I'll try to be there before they open to be sure of getting a cart, and I have learned in years past to make sure I bring a drink and a good-sized book.
I once read 3/4 of a Kathy Reichs book while standing in line!
