Yellowstone in October

Thanks for the replies everyone. We're excited to go when the crowds have diminished. However, it's looking like the downside is that there aren't as many camping opportunities, especially this year with construction on one campground and most of the others closed for the season, presumably due to Covid. According to the Yellowstone website, only four campgrounds are open right now, and in October, it will be down to only one. We're not concerned with shops and facilities being closed, as we're trying to social distance anyhow.
