to still have my left hand attached to my arm. went to boone for the weekend to ski and about an hour away, around 9pm, heard a hissing sound. stopped and poked my head out the door to see what was up and my left rear was flat. i didnt want to change it in the middle of the road so i pulled into jonas snow tubing park. the parking lot was packed gravel, not ideal conditions for jacking a vehicle. of course the jack and wrench was packed away under 3 snowboards, boots, sleeping bags, suitcases and more. and had to remove the coolers from the tailgate carrier to open the door. jacked it up, made sure it was stable, and took the tire off. put the spare and the second i got it on the jack came out from under it and my hand was pinned between the tire and fender. the wheel studs caught the end of the wheel, don't know what would of happened if it hadnt. had to call a wrecker to bring me a floor jack since i couldnt get the bottle jack back under the vehicle now that it was so low to the ground. finally got it changed, packed everything back in, and realized i left my keys at the bottom of the pile before i shut the door and reloaded the coolers. re-unpacked, found the damn keys, re-re packed, and left. god my hand hurts. many lessons learned. descent skiing. lots of guiness.
