Being the nerd I am, I made a spreadsheet of all the field trips I'd like to take...one day. You can download it here.
The places aren't in any particular order. I started with a visitor's brochure I picked up and added some places of my own (like cheese making and a worm farm) along the way.
Note: some of the places are open on Sundays, though not marked as such in the "hours" column. We might see some of these as a family but most of them we'll probably see during the week.
