I know this area. Roosevelt Road has been a public road since the base was closed. Just a block away is a baseball diamond that is open to the public. Last time I was on this little side road there was no "No Trespassing" signs or other restrictions. I drove around in the tulies there and encountered HPD (Honolulu Police Department) looking at a stolen and stripped car. He ask what I was doing out there and I explained I was looking for the remnants of the Mooring Mast benchmark. He was satisfied (after I explained about geochaching and benchmarks) and left.
Point 1: If this is a restricted area why did I not see any barriers or signs?
Point 2: If this is Federal property why was HPD there?
Point 3: Why didn’t HPD tell me to leave if it was restricted?
I can go take another look, but I don’t think anything has changed.
