Any good Museums / Tractor collections to visit in Missouri?

I am taking a trip to Welters this next week and would like to knock around Missouri a couple of days. Any suggestions on agriculture type museums or MM tractor collections that could be seen while I am there, or any stops worth making? Also I have a trailer that has room available if someone needs something hauled back to Texas. Thanks for your replies!

I have a 140 White I need hauled back. Its the yellow one.

You could drive up to Bonner Springs, Kansas and visit the Ag hall of Fame.
Its a little ways west of Kansas City

Here's a list I made last year of Mo. shows. This has my personal observations, you mightn ot pay too much attention to those;
OK Steam Threshers Pawnee OK. May 3-4-5 2013 Pawnee OK.
Steam & Gas Engine Show
Great show, good food, lots of parts trailers, 3 days full of activities, look at handout schedule.
Call Pecan Grove Motel 918-762-3061 a month or two in advance, or more
May have to drive south on Hwy. 18-S, 22 miles, and stay at one of 3 motels in Charlton or Cheswick or Clinton or whatever it was. 3 very nice motels, but full.

Another thought, since you're here in the vicinity; you might go to Velten's 1 mile east of Pierce City MO., he is a machinery salesman, and has several acres full of older tractors & implements. It's all for sale, but you might visit since you're here.
