I have a portable climber and it depends where I am hunting...
1. I sometimes climb this one tree and get about 12 feet off the ground (that's as high as the tree will allow me to get as it's on the skinny side). Best thing is it's nicely tucked in among three thick cedars in a small marshy opening with a pond to my rear. Deer migrate thru all the time.
2. Another spot is up in some thickets on an edge of a elevated field. Acorns in abundance all around and I have my chances if a deer comes in from across the field or comes in from deeper in the woods.

Basically, during bow season I need to seek concealment which means being heavily camoflagued among the tree branches and leaves. During shotgun season when all the leaves are down, I seek areas where there are 2-3 large trees almost growing within a foot of one another so I have a good background and can hide myself well.
