It's how hoarding starts, boxes and tins full of parts.
You should see my shop. It's only 12'x12', but I've got crap crammed from corner to corner. I keep having to weed out stuff so I can park/work on the motorcycle.
Just get a snow flag...er, sorry...get a pole with a flag on top to mark where the motorcycle is.
I never considered the existence of such a thing, until I lived in a mountainous area with actual winters, and all the fire hydrants had to be marked with one of those.
