quarry lakes

i was wondering if there’s usually an admission fee to enter quarry lakes. i brought cash for both the entrance and dog fees, but when i visited on sunday, november 10th (which wasn’t a holiday), there was no charge. although tomorrow is veterans day (november 11th). are there specific days when the park waives fees, or did i just happen to visit on a special occasion? only asking bc i pulled up in my car to the little pay box and ppl drove around me and i felt dumb lol,, thank u :3
