They usually leave open and leave a note on your truck to pay when leaving. Nice folks around there. I always leave a note on office if im going in early. But sometimes they don't gey up early to open for you. So its a gamble. There are a few not so desirable ramps open 24 hrs if interested pm me. I bowhunt that lake so I know many. 6 am dousnt cut it when your in a kayak
Keep em tight!
