I love TTM as a Father-Son activity. I blogged about it here, if anyone is interested:

The gist of the post is that TTM is such a rewarding activity for kids, that it actually teaches them to write. I couldn't bribe my kids to write a school assignment with a positive attitude. But they have never complained about writing for TTM.
And I agree, the best part are the surprises you get. Carl Erskine wrote my kids a very nice note. George Shuba included a book for them with a note. And Don Mueller, RIP, also sent back a note and a nice inscription on the ball.
I also use sportscollectors.net. It is very helpful for knowing who is worth trying for and who is not.
Would love any suggestions and tips!
