Collection of Marbles-Jar Full. I remember spending hours shooting just to get the perfect blue cleary, and there it is, right next to what appears to be a blue cleary boulder!
I also ran across this set of Richard Scarry's Look and Learn Library. These books were a fun way to, well, look and learn. The worm used to crack me up. If you have kids that are just learning to read, these are highly recommended.
I was never a Nancy Drew fan, but I did notice that an almost complete set of the first 44 books are available in four lots (1, 2, 3, 4). They are already going for a lot of money. I was dismayed to find that this collection does not include the controversial "Clue in the Clock."
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
