Thanks guys. I still have my old Schwinn from the accident. I'll give it a practice try. Does a new valve come as part of the tube usually? I can't see in the videos where they move the valve to the new tube. How do I buy the correct size tube?

I feel like maybe a patch kit might be a good idea. I tend to ride with my kids and other inexperienced riders. I can't carry every tube, but I might be able to whip out a patch kit and save the day. Maybe one of those CO2 things. Sound like a plan?
