But it does sound like you didn't know how to repair a flat. Any hardware store and most gas stations will have either a plug kit, or some of that horrible blow-in sealant in a can. Either will get you back on the within an hour.
(Fyi, if anyone reading this does ever use that sealant stuff, when you get to a proper repair shop TELL THEM about the sealant before I pop the bead and spray it all over the shop.)
