I've left my sunglasses in the truck ( wear prescription ) - remembered about 8:00 as sun got real bright.
Left lunch home 3-4 times.
Forgot rubber bands once for planers.
Left camera home - on day C/R one of biggest Rockfish alone.
Once left scuba dive mask home - found out after wreck had been grappled
Had to leave it on a jug and go back later.
I'm lucky in fact boat can stay safely loaded and often have day or two to prepare any gear changes.
