Can anyone recommend any ideas for the storage of taxidermy (full mounts, shoulder mounts) in a cold dry climate (Colorado). Am thinking of renting a storage unit but not sure if they should be sealed in plastic, left open, treated somehow?

I'd appreciate any ideas guys...

Im storing mine in a climate controlled storage rental place. Maybe they have them there.

climate controlled for sure!

Left open would be ok,wrapping in plastic is not good. If for some reason there is any moisture the plastic will keep it in and cause mildew.

I would cover with blankets.

Rock,

I know there are several Sportsman Warehouses in Colorado. They will allow hunters to display trophies in their stores, if they have the room.
This is a very safe, climate controlled environment with no storage fees. The mounts will collect dust if you have them there for an extended period of time. You would be allowed to go in and dust and clean them off periodically. Sportsman's has very specific paperwork which they keep a copy on file,keep one on the back of the mount plus give you a copy. This ensures that no-one can come in and remove your mount.

Just another option I thought I would throw out there!

Kind regards,
Mary

Very good thought Mary. I have a couple of bears I have lent to my buddy who owns his own gunsmith shop.

Cheap way to store critters store when room is an issue. Schools and hotels are another idea.
