You know, it isn't anything I "buy" - but whoever I go somewhere, I always pick up a "neat rock" - particularly a beach or any cool place! I used to be limited to three rocks as a child, so I didn't fill my folks car when we made a beach trip! Drove my mum-in-law to Gloucester yesterday, to see the "Fisherman's Memorial" statue, and we then walked the beach for a little bit and sat on some big rocks. I didn't get to spend much time searching, as the day was her gift, but did end up with one neat rock, which doesn't look like much until it gets wet!
