I just dealt with it b/c to me it was a small step to start living with a semi dirty truck with kids.
1. car seat indentions was the beginning!
2. food crumbs to keep the kids happy while babies
3. more food and crumbs while traveling
4. oh yeah, also forgot to mention the occassional projectile vomiting while traveling...crap gets everywhere, ha!!
5. kids got older moved into booster seats, still have indentions, but less messy food wise but not tracking in mud and all kinds of things from sports and taking there buddies places
...why did we have kids again, ha!!!!???
