Yes, the government shutdown affected me, because I live near a national park. There is a place I like to go within the park, and I wanted to go on a Saturday. There were barriers in front of the parking lot, with a sign saying that they were closed because of the shutdown. I had to do something else.
The fact of the matter is, the government planned for something like this and kept a lot of money in the off-chance that there would be a shutdown of each particular service. I did not notice a single discrepancy in any service, and it all functioned normally in my eyes, but I am not closely tied to the government in any form for my benefits, and payments alongside of that.
