Minneapolis area recommendations?

[scubagrrl]

Well, I'm going to Minneapolis for work pulling out some old equipment, so mostly our vehicle will be full so no real room for a cart/wagon.  I would like to get something collapsible for the purpose of dragging all our gear to spots like those quarries, but it will have to be a different trip when I have room in the car. heh 

Hopefully Square Lake will be a worthy dive, I think we're going to work Thursday, hit the Aquarium at Mall of America on Friday and dive all day Sat then drive home on Sun.    Then two weeks later we're taking dry suit certification classes and exploring going that route.  I really prefer diving wet, but I'm also a temperature wimp and don't like to be out of my wet suit in cold weather while wet.  We even bought 7mil hooded shorties to wear over our 7mil suits so we could dive earlier and later in the year.  I still ended up not diving as soon or late into the year as I would have liked and don't get in as many dives.  I'm also afraid to go wreck diving even though I live right on Lake Michigan because I'm afraid I'll freeze on the boat ride home. LOL 

I was reading about all the mines up near Brainerd today, sounds like a lot of fun diving up that away as well?
