We sure enjoyed the St Augustine beaches!
We were able to drive on the sand, and could haul a day’s worth of tents, dog kennels, chairs, etc. so we had everything we needed with us. 
With three dogs, we couldn’t have carried it all and managed them too. At other beaches we chose to take the pups for long walks then leave. Being able to have a vehicle near where we wanted to hang for the day completely changed how we could spend the days.
Oh, those dogs still got plenty of walking, too. And we had all the comforts and shade we needed to enjoy our books in the sea air. We had lots of time for relaxing and making seashell fairies!
