Had a great time at the Neptune Festival last weekend. Pretty hot, but lots of nonprofit booths were selling water for $1 each, which was great. The sandsculptures were amazing, and I liked the fact that they now have a temporary boardwalk so you can get right up to the sand sculptures without getting sand all over your feet.
Best advice: next year we'll get there about 9:30 on Saturday to get parking. There were so many people at the event that parking was tough to find.
