In Search of Open Water event....

I swam the Great Chesapeake Bay 4.4 mile swim last month in Maryland. I swam the Save the Bay 1.7 mile swim in Newport, Rhode Island last weekend. Both were excellent open water events and I would highly recommend both events to all open water swimmers. Now, I am looking for another open water event to put on my calendar for later this year or next year. Distance should be between 1.5 miles and less than 6 miles. I live in Winchester, Virginia but am willing to jump on a plane to almost anywhere in the United States if the swim is well organized and recommend by other open water swimmers. Any suggestions? Thanks so much for your input....
