Unique Hobby

Some people have really strange hobbies. A friend of mine who lives in Australia enjoys walking around in the bush every weekend to look for unique rocks. He’s really interested in geology and would invest lots of time looking for little rocks, polishing them in his rock tumblers then displaying them. I saw lots of quaint little hobby shops catering to these hobbyists the last time I was down there and was quite impressed. Here, it would be difficult to find a shop to cater for your unique hobby.
