regarding walking canes vs. golf clubs:
Back in Feb, I had to fly for the first time since I broke my back. Obviously, my cane went with me. In JAX, they took it from me, looked at it, handed it back, and I used it to walk through the screener. In DFW, they insisted on sending it through the xray, and had me hobble through the screener without assistance. (And got weirded out when I tried to touch the screener for support, since apparently that makes the screener do strange things.)
Regarding flashlights, in JAX they were interested in the Mini-LGI in my jacket pocket, and a stainless steel pill case on my keychain. DFW did not care about anything. (6P, 6Z, ARC AAA, AA Mini-Mag, Photon, a couple of laser-pointer/pen combos, plus the Mini-LGI.)
