Speaking of, has anyone used the owl&mouse software? i couldn't find it using the search engine, so i don't know if it's come up before... but Big Man LOVED it(still does, but doesn't use it as much anymore as he's moved on to other subject loves, for now...)
it's a fabulous way to learn world / US geography and major monuments/statues/etc - which leads to great history conversations.
