First and formost you need to bring an open mind and a willing heart. This retreat experience can and should be a life changing event. Leave the "contempt prior to investigation" in the drive way at home.
Material items to bring;
A chair - beach folding chair or a "bag" chair will work just fine. We set chairs out on the front lawn by the lake for morning meditation.
A flashlight - the grounds are well lit, but you may need to get into your luggage in your room at night without waking your room mate with an overhead light.
Your Big Book and 12&12…. Why would you leave home without them?
Bug Spray - It is usually cool enough that bugs are not a problem, but better safe then sorry.
Warm clothes - There is usually a chill in the morning and evening at this time of year. It can get into the lower 40s so be prepared. You should also check the weather web site for the Leesburg area you can use this link.
Leesburg Weather Forcast
Rain poncho or rain coat, Florida weather in the spring can be wet!
One nice outfit - You may be asked to speak and if you are we would like you to dress up a little as a sign of respect for the podium.
A friend - or several friends. This is an experience you will want to share with someone. The drive to and from the retreat can be another fulfilling aspect of the journey.
