I went into their parking lot and near the "office check in" sign, but didn't notice any red gate. Never been there before, so I wasn't sure where to look. The only one that I saw was the yellow one as you get back on to Mandy Rd. Had to take a pitstop with my son by the boat launch for a few minutes, but an appointment in Oly at 1:00pm meant no real fishin' time.
