Looks great. That's exactly what I'm planning but I luckily only need one pole. Problem is I'll be hanging 2 hammocks from it (already have 2 trees but I want to hang 3 hammocks). Do you get much flex on the poles?
I'm stuck with this sandy Florida soil so I'm not sure exactly how deep I need to sink the pole. Looks like a nice setup that the spouse, neighbor, HOA can't gripe about.
