DanL, nearly all of Cedar is on various private properties, and access is hit and miss (there are no signs which specifically permit fishing). A few landowners have their "pet" stocked fish, and obviously don't want to see fisherman. I personally have never been chased off.
Unfortunately that poster's entitlement is all to common in the fishing community, which I attribute to the PFBC's failing business plan. More people would gain access is they realized that if you give first, you often get e.g. ask for permission, be "seen" collecting trash, etc.
