Our last 4 crossings into Michigan were at the Ambassador Bridge without problem.
I always cross with a full fridge/freezer -tell them what I have and get waved through. Just know about the few restrictions. A call to the
Agri. Dept to see if anything has been newly added to the list is advisable. Get the person's name and take it with you and if you are questioned at least you can indicate you tried your best to obey their rules. I hate having to stop and shop - would much rather spend the time getting to our destination and shop when we get there. Usually works.
