Just got through making a reservation at the recreation.gov site.
What a steaming pile! I finally got the campground and campsite that we wanted. Tried to check out and it wouldn't let me as I didn't have a browser they liked.
Went back using Internet Exploder booked site and days, then my wife said I'd like to add a couple more days. OK dear, clicked the "Modify" button to no avail, had to start the whole process over.
I had zero problems with the old site, I find all to often sites that are working just find are reworked and turned into something difficult to use. I guess the programmers need to keep busy to justify their existence?
