That sounds fun TrekDianna! I love riding on closed roads. Where is the McKenzie Highway?
Yesterday we rode through four cities outside of KC (Prairie Village, Overland Park, Merriam, and Shawnee!) to find a Trek bike shop. I have ordered a couple of tires for my MTB to be delivered to that store this coming week, and we just wanted to make sure it was ride-able. Only about 12 miles round trip, but we tacked on some for a 20-mile ride.
Here are some photos from our ride, which took us on roads, through a couple of parks, on on bike/ped paths. What a blast! I just had to pose outside of the (closed) Trek bike shop with my Trek, of course!

It's pouring cats and dogs this morning, so it is a good day for off the bike activities. Hope everyone has a nice Memorial Day!
