Woke up early just to reserve campsites and then kept hitting this error on Recreation.gov :(
This was so frustrating -- I've had reminders set for this day since a month ago, and I made sure to log on at 6:55 am local time. Found the perfect weekend for a overnight camping trip to the Enchantments, hit "Book Now" and kept getting this error message ("Our system has detected abnormal activity from your computer network. Please try refreshing the page or re-logging into your account). No VPN, and hard reloaded the page after the first time but no dice.
Happened to four other dates, and now I'm left with nothing. Can I get an F in the chat pls.
