I want to go tomorrow. It's a Monday in early August and going to be sunny and 90's. What time do I need to arrive to get a parking spot? Thanks.

As early as you can! 9am. Lot is small and you can't park on the road!.

The lot is definitely limited i went last monday at about 11 AM and had to circle around for about 15 minutes b4 someone else left

From my experience, you might want to be there when it officially open at 9 a.m. parking lot is very limited

Someone said you need a county parking sticker to park. Is that true and if so where do we get one? We are from MA.

Is this stroller friendly?

You neec a county parking sticker

The earlier the better.
