I probably notice it more because I am sensitive to a lot of chemicals that don't seem to bother most people. The chemical solution that is commonly used in tanks contains formaldehyde. It is bad to breath, and bad for your tanks. In a few parks I smelled it pretty strong, and in others it isn't as bad. Some parks have a rule not to use those chemicals, but people do anyway. My guess is a lot of people just don't think much about it because they don't have allergies to the chemicals.
How do you know what you are smelling is formaldehyde? There are plenty of tank additives on the market that are formaldehyde free. Personally I have never smelled something like that at a campground unless it was actually near a portable outhouse.
