Last year, I started with "Meet & Greet" - events while travelling because Geocaching is not only about finding caches, it is also about meeting other Geocachers. While being in the Jo'burg area, I like to meet Geocachers who could give me some advice about "Do's & Don'ts" while caching in SA as well as on interesting caches.
I could give you some ideas about Geocaching in Europe and I will bring a few trackables along 
This is a BYO event 
C U soon & happy caching,
