You're very welcome, fellow Laura fans. Some people fly into Minneapolis, rent an RV, and do the circuit - sorta covered wagon 21st century style.

The distances aren't that great.
DeSmet, SD to Walnut Grove, MN is 110 miles.
Walnut Grove, MN to Pepin, WI is 205 miles.
Pepin, WI to Burr Oak, IA is 120 miles.
Burr Oak, IA to Spring Valley, MN is 40 miles
This is from the front of the Masters Hotel.
Again, fingers crossed for all of you to see these wonderful places!
