While fishing over on the Bitterroot this spring there was a guy at the
flyshop with a car top fly rod holder. The beauty of this rod holder was
that
you could store the entire fly rod in it without breaking it down or taking
the fly reel
off. It looked like a metal/aluminum 10 ft. tube with a lockable door at the
fly reel.
It held two or three fly rods.

I've googled and found several option, but none like I have described.

Anyone know of the manufacturer or retailer?

TIA,
JT
