I wish I had brought ____, because____.

What are some things that you had wished you had brought along on the trail?

Here are some:
1) I wish I had brought a 12v drop light, because it's awkward trying to hold a mag light in one hand while trying to work on the starter with the other one.

2) I wish I had brought a saw or an ax, because it would of have come in handy trying to remove fallen trees/branches from the trail.

3) I wish I had brought a spare fuel pump, because - well, I'll let you guess...
