Sue Neal and I had several stopovers on the way to Fargo ... Hannibal MO to see Samuel Clemens boyhood home on the Mississippi ... we took a boat ride on the Mississippi River and visited the museums.

We stopped by Pikes Peak State Park in northeastern Iowa for some great views of the Mississippi. It seems Zebulon Pike was there earlier before moving west ...

We stopped by Seed Savers and they were having the annual conference on heirloom seeds. Lots of interesting projects and plants. We also went to their orchard where they are saving and protecting rare apple varieties include a red (inside and out) Geneva apple. They have a great catalog you can get for your parents or the gardener in your family.
