Questionable tube, no way to fix a flat. In these parts Walmart is the bike shop. I can get tubes and a pump there. Closest one was back to Big Spring, 12 miles. Next closest was the direction I want to go. Seminole TX, 75 miles
You can order and ship gear to a post office ahead of your arrival. The PO will generally hold packages for 30-days, but it's best to do a little set-up and confirm in advance.
