Two Tides Sour Fest

Has anyone been to Two Tides sour fest (or any of their festivals, really) before that could share what it was like?

I’m very familiar with Two Tides but have never been to one of their festivals and just wondering what the details regarding pours, etc. are. It looks like the festival is free to enter (from what I can gather from google/their socials anyway) so assuming it’s likely pay as you go. Are they sample pours or do you have to purchase full size pours? They don’t seem to include this info in their posts about their events and we’re coming in from out of state so trying to gauge how much time we’ll want to spend there, how much cash to bring to the fest and if we’ll be up for hitting up a few different spots after.

Thanks in advance!
