Replying to Help me fight a ticket

So i was playing in our homecoming football game yesterday. i parked my car in a spot where people ALWAYS park. the parking lot was absolutely packed and there weren't any spots.

so i left my car, and during the game, i heard them announce "if you are parked in a firezone, you have 10 minutes to move your car."
of course i couldnt, i was in the game, and i didnt even know if it was a fire zone.

well i get back, and there is a ticket for $50 on my window.

well im a volunteer fireman, and so i get an alarm today that was right down the street from me. i walked over to check it out, and my cheif and the cop that wrote me a ticket were there.

i mentioned to the cop that i was pretty sure he wrote me a ticket yesterday.
well this cops a huge dick, as i've been told, and as i found out.
he went off on me about parking in a fire zone, especially as a firefighter. he was telling me i should fight the ticket so he can embarrass me in court.

well this cops a cock. i want nothing more than to beat him in court.

here are the facts.

he said he gave me the ticket, but it is definitely not his signature on the ticket.

there are other fire zones at school that are marked in yellow with lines through it that say "fire zone", but this area ONLY had a yellow curb.
what makes it a legal fire zone? i feel like i can get them here, cuz there was nothing but yellow curb to mark it
