Tree stand etiquette in 410

[walk in the woods]

Trying to get an idea of where to put my tree stand in 410. I have some rifle experience but new (and excited) about bow in 410.

Walking around there are alot of tree stands that get left out year round. I don't want to be too close for safety and general manners.

Questions:

1. How close to existing tree stand can I put mine?

2. If there is a really old looking tree stand, made from wood, that looks like it hasn't been used in years....can I put mine near there? Can I use the old one?

I know there are probably no definite answers to these questions but looking for general ideas. I realize that solitude is part of the appeal for hunting and trying to avoid being "that guy".
