As a father of a 3 year old boy, there are many places I want to take him but he isn't quite old enough or we can't go today. I have a list in RTM for places to go (an extension to my someday maybe list) and when we have a free day I skim the list for ideas where to go. I initially started by removing places as I went to them, but places that are not "regular hangouts" I keep on the list.

Whenever I hear of a place I would like to take my son now or in the future, it immediately gets put on this list. I typically keep places that are too old for him on my someday maybe list and everything else on my field trip list.
