I know this is quite late to ask but I am leaving for Maine in the morning. Going to wedding in Kennebunk then on up the coast next week. Will be doing some camping and expect to get to Lubec. I expect to cross over to Campobello Island and maybe stay a night or 2. Now for the question. Should I expect any problem from customs going or coming if I have my cooler with food in it? I have heard that some foods are not permitted into Canada or the US.

Any other advice would also be welcome.
