Ka ching!!! Yay team, you are doing great!!!! Our total is now:
1481.5 miles! Wow we are almost halfway.
We have a little over a hundred miles to go to be in Chamberlain SD!!!
:cheer"
I will try to keep up with the scores a bit better until we find her!!! I hope she is okay!!!
They were closed when we went there. I find it ironic that when I was little my parents went to South Dakota with my brother and I was left behind because I was too little and then I went there with my children and my youngest was too little to remember. I think I am going to have a plan a family vacation for the future to SD so we can visit some of the attractions. I am kinda interested in seeing the Flintstone village.
but I didn't WANT to see the Corn Palace... my brother and his family were not very happy with me because I stayed in the van while they went inside. I am just not into country LOL... grew up out in the sticks and saw all the corn I cared to unless it is on my dinner plate.
They thought it was wonderful though.
(I can say that; I'm single!!!) 
I was born and raised in Iowa so I can relate to see corn alot. I guess I just wanted to be able to say yes I saw it.

You have mentioned most of them.. but you didn't miss anything inside the corn palace the cool part is outside. The doll museum is awesome. Chamberlain is really beautiful and the Missouri river runs right under the interstate. Very beautiful and very full right now. Another place to see in Murdo SD is the car museum...hubby's fave. Then of course Wall drug who wouldn't want to stop there! They have alot of stuff even a robotic Dinosaur! They advertise with billboards all over the united states...even as far away as NY and maybe even out of the country. Miles and Miles and Miles of nothing.. Then we will come up on the badlands...beautiful. Then the Black hills really really spectacular especially Spearfish Canyon.. beautiful. The 4 heads of course and Crazy Horse's new carved mountain (not finished yet but stunning so far)...but then...Sturgis Bike rally, well that speaks for itself.....just some useless information I thought that I would share
