Oregon campgrounds where dogs can't hear fireworks?

At the risk of being a "downer" - my fear would be that ANY campground on the (incredibly popular for camping) 4th of July is going to harbor people with fireworks of their own.

What about staying in a hotel? Close to a noisy expressway to drown out the noises?

Avoid any kind of lake or stream - we live on a lake in Michigan and the celebrations with daily fireworks last for a couple of weeks before, and maybe a week after the actual holiday.
