USFS parking ticket??

I didn't read all the responses so sorry if someone else made this suggestion but I would contact them to see if its legit. If it is then find out how you can appeal it without costing you more than the ticket. Sounds fishy to me. Especially if you know you were not blocking the gate from any large forest service rigs that might need to get in.
I don't think photos of how you were parked would do you much good. They will just say you moved your truck and then took a photo. Now if the guy who wrote the ticket has a photo then maybe you got something.

First-Go to the local agency office and talk to them. Video it.
The fed rangers I have dealt with lately leave a lot to be desired so I wish you luck.
Then-court with time stamped pictures and video if it helps your case.
