i was on a bike ride today just screwing around town and i got a thumb tack in my tire. i didnt have any spare tubes with me but luckily my friend did. so i changed out my tire, blew it up the best i could and headed home. when i got home i was in my garage and i heard this loud pop and my tire busted again ding nothing but sitting there aginst the wall. so i took out an old tube i had that had never been used and i patched one hole then two then three then four before giving up realising that there was no hope in finishing my ride. i had no hope in getting another tube because it was sunday and it was to late in the day for any stores to be open. so i just didnt have any luck.
