Just found out that I will be town for the Oyster Festival and was hoping to get some input. Is it a good time? The website makes it sound like two great days of food and music. Is there an admission charge? Do you buy food/drink tickets? If so, are they cash or can you use a credit card? Do they have ATM's nearby (I see that it takes place in a park by the river)? Thanks in advance for any input.
