Well I just jinxed myself, yesterday I gotten a flat on my 'main' tube and without thinking much about it I change to my spare tube. Murphy was having a field day, because later on that day I came to a bicycle with another completely flat tire. Of course, I cant patch it due to the hole being more of a cut then a hole.

So a bus ride later I came home and examine my 'main' tube and guess were the leak was? it was Coming from the glueless patch, SOB! I lost a perfectly good tube because of that glueless patch...
