I was there Prez weekend with a medium sized group, we were not hassled by anyone and we had all different types of rides, dirt bikes, quads, Rzr's, buggies... etc. Every single vehicle had a flag, a registration sticker etc. I wonder why we weren't picked on? Maybe if you are being singled out for not having a flag, or registration or speeding or being dangerous... you should just comply. Before I went to Dumont for my first time, I looked on this site, found the rules for the area and made sure I was able to fully comply. My group and I had a great time! Can't wait to go out again next month! Just my .02
