We did it!
Despite one kid (Ella) getting carsick and the drive taking longer than we had planned, we finally made the road trip to Southern Minnesota and visited Tom's Mom -- Grandma Della -- at her farm!!
Our visit was shorter than we had hoped, but it was a nice time and all four of us are looking forward to heading back when the weather is warmer and there's grass on the ground, rather than snow.
We have a lot of exploring to do!!
