Rear Differentials and Playtime

This past weekend, Nana and Granddad came to visit! While Brian and Granddad worked on replacing the rear differential in Brian's truck (to change the gear ratio for better acceleration - are you impressed with my car knowledge? I actually know vaguely what this all means!), Nana, Nathan and I spent a lot of time playing together. We had a great visit, as usual, and are looking forward to seeing them again in two weeks for Nathan's birthday party. Can you believe Nathan's almost a year old? Incredible!
