Reedsburg is okay, but I think Baraboo would be a better choice. Baraboo downtown is on a square with a decent number of shopping and dining options, it's more charming and has the historic Ringling Theatre, which provides a bit of culture (they have plays there as well as other community events). There is also a great coffee shop/cafe on the square there, called Java Cafe. I think it's owned by a San Francisco transplant. The Village Cafe downtown is also good. There's a great used book store and a fabulous kitchen and housewares store, Bekka Kate's, that rivals anything you would find in a major city. I don't know about the library. It's also close to Devil's Lake State Park, which is great for hiking and outdoor activites. The one negative for Baraboo is that the 400 State trail (bike trail) starts in Reedsburg. There are plenty of low traffic roads to get you over to Reedsburg from Baraboo, but they aren't trails, and it will be about 20 miles of riding on backroads to get you from Baraboo to the 400 State trail in Reedsburg.

I like Reedsburg, but I'm not sure the downtown is quite what you are looking for. It does have a good library and all the things you mentioned, but I think Baraboo is just a little more vibrant while still being a small town.

The commute from Baraboo to the Dells is about 15 minutes.

I think you nailed it right on head, Paige! I love Reedsburg, but as Paige said Baraboo may be a better fit for you. Devils Lake is my favorite place in Wisconsin and its just beautiful there, check it out.
