I haven't cleaned out my trunk in 3-4 years. This is just a guesstimate of what is in the trunk since I'm at work right now.
spare tire/tire iron/jack
2 liter soda bottle filled with 50/50 mix of antifreeze
small bottle of oil left over from last oil change
good jumper cables
mini air compressor that runs off cigarette lighter
road side emergency bag with flashlight(without batteries), extra jumper cables, reflective triangle and bungee cords
a "disaster" bag that my dad put together for me (he is certain the world is going to end soon ) that I have never actually opened to see what is inside
now for the really random items:
a pastel Picasso style painting of a violin (ruined from being in the trunk for 4 years)
a set of 3 small acrylic paintings on canvas'(also ruined)
a bottle of either seed beads or glitter
a spoil of black thread
3 yards of elastic
a 6"x6" block of wood
Maybe it's time to finally clean my trunk?
