The guys are right... I think, lol the cobwebs are fuzzy and stuff. I believe the first actual Loc-On stands were created by the original companies founder in the late 60s but didnt come on until the 70s. Likewise Baker was the first name in climbers on a national scale also in the 70s. God how I DONT miss those stands. Todays sue crazy public would eat a product like that up. I was only 16 when I had my first "near fall" from high atop a pine tree in MS during a late summer scouting trip. Those things were DEATH TRAPS.

I dont specifically remember the first "crotch stand" but have seen old ads in magazines for them that date back too the late 60s, early 70s as well.

Thats as early as I think anyone "went nationwide" with the idea of a commercially available treestand.
