Check Zoning. Some towns are very specific on fence types and heights. That may limit your choices some. If you live in a zoning free town, I envy you.
We live in a very rural community. Zoning in our area is unheard of, really. I called to check the zoning yesterday, spent an hour on the phone with a confused clerk who had no idea that places have zones for such thing. *LOL*
Echo post #2, check your local zoning = task #1. Some localities are perfectly happy with a 5 or 6 foot fence and go completely bonkers with an 8’ fence.
