Oddly coincidental, since my 10-y-o nephew just got HIS first flat of the year this evening. Popped a fresh tube in it to get us home, and proceeded to the patch pile -- 5 tubes needing attention. One was a schraeder valve tube with a missing core. . .set aside for now. Three more patched right up, no issues. But, the LAST one. . . . . . . .

4 -- count 'em, 4! -- snakebite holes, from a 'rim ding' on a sharp-edged pothole about a month ago. One patch, my last one, didn't take, so I wasted my last 4 patches -- GGRRRRRRRRRRR!!!! Oh well, $2 will re-supply me. . . . .
