Never lay your rod on the top of your vehicle,by a tree or on a table. I know guys who have lost or left their rods and most never got them back.
Don't travel with your rod out a back window. Electric windows do a job on a tip top section.
Also, keep your pockets zipped up on your vest or pouches. Know guys who have lost several fly boxes.
I did lose my cell phone on cow shoals a few years back. I missed the pocket on my jacket and didn't realize it. It may still be floating in the plastic bag?
I'm sure others have some good advice?
