The most unusual FTF prize I was given occured in a very nice cache in Lisbon. The cache in question is "Dress Code [Lisboa]" by SUp3rFM & Cruella (GCTYTF). The Lunchtime Gang, that's me and a partner, bargao_henriques, were the first to tackle this one on a very grey and stormy lunchtime when it literally poured cats and dogs. While were were sheltering from the heavy rain, we saw another two cachers, BTRodrigues and 2Cotas, who had also come for the FTF.
We ended up holed in the same shelter waiting for the storm to subside but the strong winds meant that were were getting wet sideways. Anyway, after the rain subsided, by which time we were completely wet, we eventually found the cache with the help of the owners who had inadvertently made a mistake with the clues and were sending us the wrong way.
About a week later we had an event cache and the owners, SUp3rFM & Cruella, arrived bearing a blanket for each of us to compensate for the soaking we had had a few days before.
