You will have so much fun! Are you getting a sit-on-top?
My husband and I have Malibu Mini-somethings ("X", maybe??) and we love them. We both were in our early 50's when we started. Unfortunately our nearby river, the Guadalupe is not flowing so no trips this summer. I'm seeing a neurosurgeon about some back issues and hope he fixes me so I can get back on the water next summer.
