Should I appeal to this lane violation?

So I was driving in Burlington, VT on the interstate at around 1 am. two nights ago when i got pulled over by a police officer. He asked me why I though I got pulled over, I asked him was it because of speed? & he said it was because I was driving in between lanes and straddling the lanes. But I don't recall doing this except when I changed lanes. So I don't understand where he saw this occurring. He was a little suspicious in thinking I was drunk, but found nothing on me like smell or anything in my car. The other thing I don't get is how he could have seen that when he was far away from and didn't pull me over then, but waited until I got on another highway. Also, the section he claims to see me has a hill and a curve which by then I remember I did not see him in my rear view mirror. I was not straddling the lanes, I switched lanes once without signaling, but by then the cop was not behind me, so I don't understand how he could have seen this. He gave me a ticket because he claims that I was bouncing back and forth in between lanes and drove in the middle.. which is not true. I feel like if he saw that to begin with he would have pulled me over when he saw this, but he waited until I got onto a different highway. Should I appeal to this ticket or just pay the fine of $214 & 2 points off my license? I'm only 18 & this is my first ticket.
