Thanks Daryl, that is kind of what I had in mind, although I was thinking that instead of having a permanent bottom rail just put some kind of block at the bottom of each post for the bottom rail of the panel to rest on.
Also was thinking of doing the same thing for the top of the panel and then adding the some kind of spindles. I'd like to make it easy to see through so as not to block the view. I've seen a lot of cabins with painted rebar for the spindles and they look pretty good.
I never thought of tempered glass is that very expensive, although that might be a bit harder to store safely in the winter. I'm short on storage space unfortunately ,
Not sure of the best way to attach the top 2x4 on the panel to the posts.
I'm curious Daryl, what program are you using to draw your designs.
I used to use Adobe Pagemaker years ago and loved it but they discontinued it and I haven't found a substitute that I like yet.
