Use of GPS
Having recently acquired a Garmin iii, I wonder how many rely solely on this gadget.
I find it very useful but find myself going out of my way to obtain position fixes visually and QDM's in order to confirm position, seemingly paranoid in not just using GPS.
Also I have ventured nearer to airspace than I would before as a result of the GPS.... An excellent tool but I have heard a few stories about guys/girls who use it as their primary source of nav.
