Were you hunting northern NM by chance? It might be mine! I left one on a mountainside one morning when I stopped to put on rain gear.
I've since replaced it - I like the rear end model. A little smaller and easier to carry, and I like the idea of a bull thinking that the cow is facing away from him.
Biggest problem was that I don't like to have it in my pack because I tend not to use it as often if I have to stop to take off the pack and dig it out. Last fall I made a 3 sided open top carrying pouch for it with belt loops so now it is right at my side and I can have it out and set up in seconds. I skip the stakes and just use spring clips to attach it to a bush or tree limb. Fast, easy, and light!
