In 6 years we've seen only one. It was on the wall outside the womens rest room at a large resort (begins with an R). Scared the livin **** out of my 19 year daughter. That was at Christmas and we've never seen another. The skeeters can get a little big in November. Bring some bug spray and a tennis racket for those who get past the spray. A normal swatter will be ineffective. Novemebr has ben a great time to be there. The crowds are definitely down (OK, compared to other places the crowds are always down) and other than a little rain it was great weather each time.
