Hi and thanks for joining us. 
Over the years, I have read that there may be more Pucks in the US than you might think. However, because of the size of the country, they can be well hidden. 
As well as this forum which is a great source for information and advice, we also have an Eribafolk Facebook page and about 18 months ago we helped one of our members, Kristy Guzik, to start a Facebook group called Eriba Pucks in the USA. https://www.facebook.com/groups/1509591689291126/
It might be useful to join them too as they may know of a Puck hidden away somewhere.
