>problem is how do you keep people from walking into it including yourself
This has been mentioned here before, but Paul Martin and others solved this by installing a removable pitot probe. Just a short stub of aluminum tube that inserts into a larger piece that's installed in the wing. Part of preflight is to insert the pitot (after removing the plug you've inserted to keep wasps and stuff out). Part of postflight is to remove and stow the pitot probe and stick your plug back in. Needless to say, you also need to have a "remove before flight" streamer on the plug or you won't have airspeed indication of any kind.
