Several. Heck, when I started bowhunting there was no such thing as a climber or even a stand available. I remember climbing up in trees a couple times and hanging on to limbs for a platform, but mostly you hunted from the ground. I remember when the first Baker climbers came out. I bought one instantly and thought I had died and gone to heaven. That was just a platform and you hugged the tree and pulled yourself up. It was great..... until the first time it lost it's bite and I slid down the tree like a train wreck. Took all the skin off my arms and face(chin and nose). Hunting from the ground is no problem, you just have to get everything right, the wind, your movement and some luck. Even in recent years one of my best spots was a ditch running through a big field. Another one was sitting on a dove seat under some washed out tree roots in this little stream watching a stream crossing.
