We have camped at this campground numerous times over the years. We usually reserve this particular site, but have been in others at times. This is the first time we have had the misfortune of discourteous neighbors. Generally we are very friendly with those camped near us, but this group was pretty much disinclined even to say hello when they moved in. So we just chattered with other campers.
As far as moving to another site goes, the campground was full. And no, with this group, there was definitely no alcohol involved.
Hopefully our next stay (in the same site) in August will be better.
