My wife is wanting to get a privacy fence for the backyard with the tax refund this year. Just wondering how much difference there might be in price/maintenance/installation between the wood type and vinyl type. Will want a drive thru gate and probably two walk thru gates. Also, while we don't live in a "high crime" type of place by no means, I've wondered about the ability of someone being able to get into my shop unseen behind this type of fence vs chainlink or other types. Thanks for your opinions!
