No, they did not let me in. I have driven the bike in w/my truck ever since, bit isn't that hard to get in otherwise. Just have to wait for them to be busy and drive up.
As far as sound and spark arrestors, there is no tckt at the gate, they just don't let you in. Now if you are already in and you decide to take your arrestors off and they catch you, they will then tckt you.
