hey i am new to this but. there is an ok place behind the norfolk airport off of burton station rd. (near where people use to race at). i have been out there a few times. their are a lot of people out there. mainly with dirt bikes and four wheelers. but if you stay away from them it is ok. a few weeks ago the cops came out there twice and just said to stay on the one side of the tracks and nobody will care if you go back there. its a cool spot. you should check it out.
