So glad to hear you were able to spend time together. I have so many fond memories of projects with my grandparents. When I was that age I spent more time at there house than mine in the summer tinkering on projects. Weather woodworking, lawn work, gardening, hunting, fishing, exploring in the woods.... Special times! I imagine he will never forget this quality time together and he will always have a unique project to stir up those memories of you!
