As someone who did much of his dissertation research in the Brown County Historical Society and Museum, I can tell you that you are in for a treat. While not very large, the museum has a wealth of information about the German community in New Ulm--in particular, the German-Bohemians. If in New Ulm, also go to Schell's Brewery up the hill outside town! Better than Anhuiser-Busch Brewery, in my opinion.
Greenworld is the place to go in town if you want a tree. From my friends at Dordt College who know these types of things, they offer comparable deals to other big city places. Especially for such an agricultural area such as here, they have some competition but always seem to do well. Ground Effects in Sioux Center would be another option that our family has tried for gardening and for stump removal.
A nursing college primarily-- this college has cooperative agreements with other colleges in the area, including Dordt College in Sioux Center, IA. The nurses trained at this school are very good --- as I've had several of them at doctor office visits in the last several years in Northwest Iowa. Personal attention is a plus here.
A Catholic College that tries to stick close to its roots, Briar Cliff is literally on the cliffs---or at least a ridge, outside of Sioux City. Briar Cliff is booming in recent years, in part, due to the creation of a football team that can now draw upon the parochial schools in the area. From all accounts, though, despite anti-football sentiment from some academics, it has helped rather than hurt the academic situation at Briar Cliff.
There are quite a few small liberal arts colleges in Siouxland (area from Sioux City to Sioux Falls) and Morningside is one of them. Surprisingly, nearly all of them have great reptuations and traditions. Morningside is, like University of Sioux Falls, a football school. But they are also well known for the English department and their business department.
If you've never been to an Indian casino, then stop by here. The Argosy casino in Sioux City is actually nicer, in my opinion, but for unique, stop by the WinnaVegas casino just off of Interstate 29. If possible, try to time your stop with one of the pretty good entertainers that they have stopping by the casino. Don't make a special trip here, thoug, if you're not planning on driving by.
A combination playground and toy store, Thinker Toys is not just another toy store. They specialize in lego sets, scientific games, erector sets, and other hard-to find games that you might normally have to order online--especially out in the midwest. The prices aren't the cheapest--but its a great place to check out different types of toys for the kids. ALso, there's an indoor playground for the kids--I've seen better--but its still worthwhile on some of the snowy days in February!
On the outskirts of Sioux City up Hamilton Blvd til you're almost in Plymouth County, this is a fun place to go miniature golfing with the kids and to also practice on your drives. The miniature golf course is clean and new--but not one of the massive, trick featured ones that you can find in resort areas. But compared to some that are flea bitten and small, this is a great place to take the family.
With a growing non-traditional age student and commuter base, the school is perhaps best well known within the area and beyond for its NAIA football program that seems to win every year. They do throw alot of money at the program and focus upon it alot. Their academic reputation, however, is not as strong.
Great local college with national reputation. This college has omved around a bit, though over the years. For awhile, it was located in Canton, SD about a half an hour drive south of Sioux Falls (the old buildings are still there). With a tradition going back to Ole Rolvaag, the Scandavian writer, it continues with great students who are also very sportsman like in the contests I've seen.
