I do have the cheap stretchy plastic strips. Last year I got 2 punctures in a rather short time due to the tape being shifted to the side slightly. Now I check the rim tape whenever I have a flat. For now I put a patch on the tire and will wait to see what happens. It does bother me though not being able to find what did cause those 4 punctures in the same spot. Did 70 miles yesterday without any problems. Maybe whatever it was fell out the tire without me seeing it.
Thanks to all those who gave me input, this has been a learning experience for me. I am going to be more diligent in finding the cause of a puncture the first time it happens. Time for me to buy another minipump..
