Getting to closer and closer to a complete collection of US State maps. This time South Dakota thanks to Zach and his mom Carolyn. The deal with this swap was Carolyn sent me the card and asked that I send one to her son Zach in return, not her. Easy peasy. The kids helped me pick out a card of Niagara Falls and I told him all about our most recent trip in August. Hopefully he gets it soon.
