What do you buy for the dad (66...widower of 2 1/2 yrs) that either has everything he wants or if he wants it, he goes out and buys it before I get a chance to? He does not like "trinkets" or things to just sit around and collect dust. He usually says not to get him anything unless he can eat it or wear it...I would add grow it to the list because he has a container garden. I am at a loss of what to get him for Christmas. Any ideas???
