Mike, I definitely don't find them all in one place. Barb and I were in many, many shops along a couple thousand mile trip. I got chips in Goodlettsville, Tenn., Franklin, Ky., Jackson, Miss., Lake Charles, La., San Antonio, Tex., Comfort, New Braunfels, Gruene, Fort Worth and Texarkana,Texas. Chips from Hot Springs Arkansas and probably another half dozen little stops along the way. My wife has an i pad and we will google up antique shops along the highway. If something seems interesting we'll make a little side trip. The yard sale where the guy told me where Ridge Top was might be the best find of all. no telling who might have that little nugget of info that ties things together. It sounds like just a chipping exposition but we saw a lot of other stuff too. If you're ever in San Antonio Texas you have to see their River Walk... Both day and night. And don't forget the Alamo.
