A tip about keys..
Having too many cool keychains and crap -- almost a pound -- didn't damage the ignition switch on my '75 Monza Towne Coupe I had as a teenager, but it required a new lock cylinder when it decided to keep my keys and refuse to spin.
At 1:45 in the morning.
In the graveyard.
Where my boyfriend and I used to go to uhhhhhhhhhh partake in our favorite illegal green substance.
I can still remember the look on my dad's face when he showed up to fetch us.
