Looking for another Open Water swim and a clinic with Eric Shanteau? He's hosting a clinic and open water race Sept 18 and 19 (I think they have a typo on the home page because they wrote 17 and 18 but Sat and Sun are 18 and 19) at Lake Lanier Islands. See link for details. If you can't go on Sat due to Yom Kippur, they will still let you check in on Sun morning.
