Bugs Bunny had previously had a run-in with a big galoot of a construction worker in "Homeless Hare", and much of the same happens in "No Parking Hare". Though it's got the same sort of plot line as the former, this one is impossible not to like, as Bugs hilariously messes with every one of the builder's schemes.
One other thing that I noticed about the cartoon was the opening scene. Obviously, this was around the time when freeways were becoming a part of America's landscape. It of course got to the point where Dionne Warwick in her song "Do You Know the Way to San Jose?" described LA as "...one big freeway...". While some may view it all as progress, the freeway system turned us into a totally car-dependent society.
But I digress. This is a really funny cartoon. I almost never stopped laughing.
