I'm on the left coast but have many happy memories of a week I spent at the Lauderdale Tennis Club and hope to return there some day. Noticed your mention of Crohn's disease and you may want to look into the works of Dr. John E. Sarno, MD about stress and its relationship to many "dis-eases" including Crohn's. Good luck on your season, wish I was there, loved my cross country drive to Florida through the snow and putting the top down on the Jeep for a month in sunny Florida, while the rest of the country was experiencing the big blizzard of 05/06.
