I tried searching the forum but all I come up with is an error. Palomar mountain was suggested to us and we're thinking of heading out on a whim Friday. I tread making reservations, but they only offer 'walkup' and reservations for ADA sites. While I do have a disabled placard, it's my mom's and she won't be with us. And I don't want to be a ****** or get a fine. So how do walkups work? Are they like first come first served or yellow posts elsewhere? Can I show up early Friday and get a spot?
