Today, I had to repack the trunk of my car after having it in the repair shop. I had removed all of my supplies and gear prior to the visit. In the process, I discovered two problems:

1) Do-nut spare tire was extremely low on air pressure - aired it up completely and reinstalled.

2) My juice box type of Coast Guard survival water rations had lost it's integrity and leaked - tossed it out and restocked with some AquaLiterz that I had on hand, this time using a cardboard box as a reinforcement against excessive movement and damage from other items.

Lesson learned - check your stuff regularly!
