wow, looks as if you guys had a wonderful time!
I was on a festival for traditional musicians over here in Germany and I didn't really play as much bagpipes as I played on my Ukes... (I brought two pipes but three Ukes, which speaks for itself)
But guess what? I met other Uke players! Two, to be exactly... One of them seems to be playing for quite a few years already (I did never notice his instrument before, since I had no interest in Ukes a year ago...) he played on a Bushman Jenny. nice instrument, though it was a lefty and I had some sort of knot in my head as I tried to play on it... Went good for half an hour, but then I tried schizophrenic snowflakes on it and my head started to smoke^^
the other one was a young guy (maybe 16) with baby-dreadlocks who played drums for ten years and just started on the Uke 2 months ago. he taught himself and was not bad at all. but you should have seen him when he tried my Kala and Pono... he was like woooooaaaaarrr (*UAS hitting*), cause he has a Brüko...
it really was a fun time. nevertheless I hope to participate on a UkeWorldCongress in the states some day too...
