Look in Flyer or Pilot for fly-ins and try going to some of them. Tip: phone the place before you set off, even if you don't have to, and ask for any arrival advice they may have. I know you will find out what runway is in use over the radio but it's easier if you know well in advance and can think about it without a handful of aircraft to look after (NB it may change of course if the wind moves).
GPS is a great tool but if you find yourself not recognising anything out the window and relying completely on the little box then you are vulnerable.
