Oldest ds - will depend on his job situation. . . I may get him some thermal under clothes, etc. if he's going to be walking outside a lot. Gas cards, solar powered items. . . he's never too picky.
Oldest ds's wife - nurse uniforms, gas cards, B&BW items, fast food gift cards for when she's going to school (LPN getting her RN)
Middle son - gave me a list

His range in price from several hundred dollars (for an engine rebuilt kit for my dad's tractor that he inherited) to $5 pair of gloves. He's in the military, and doesn't generally ask for much, so I'm excited to actually have list with several items on it, in such wide price ranges. Several of us may go together to get him at least on of the bigger items.
Middle son's wife- wants travel mugs, artist supplies like paint, pencils, canvas. . . also some specific books, and gift cards.
