Love them
I, too, love the BER conferences. Like Nancy R, all but one were worth while. I wrote how disappointed I was on the survey/evaluation at the one that I didn't like and they sent me a coupon to attend another conference free. I didn't expect it, so it was a nice surprise.
I wish I could remember the ones that I liked the best. One was on solving math word problems, and the other was with Jim Trelese (who wrote The Read-Aloud Handbook). I've enjoyed others, but these were my favorites.
