Calais/St.Stephen has the international festival every year, and having lived on the Border most of my life I think this is a great idea. I grew up in St. Stephen and have since moved to Calais, and would be willing to help with an international event in any way I could.
Adults need Govt. issued id (Drivers License) plus Birth certificate. Children I am unsure of. I live in Calais and my grandkids in New Brunswick. They are 7 months, 3 and 4. We had NB id's done for all of them yes even the 7 month old. However have yet been asked for any ID when crossing into the US, and only once when returning them home to NB. It does cost much for the proper paper work, and it is better to be safe.
I would like to get a group together on the border between Calais/St. Stephen. Perhaps someone will know a good location for a cache, but not want to put one out there or does not know who owns land. We could get together talk and help each other out.
interesting idea, alot of fun ideas you could do with this
