From the May 2015 Frog Newsletter,
2015 FROG INTERNATIONAL RALLY REGISTRATIONS SOAR ABOVE EXPECTATION
We expected this year's attendance to break records once again, but no one expected the amazing response that we've received so far.
The target number for registrations for this year was 725 by the middle of July, representing an increase of about 40% from last year. Instead, registrations exceeded that number by the second week of May. We've currently filled every electric site on the fairgrounds and have had to suspend reservations temporarily while we attempt to secure additional power sources. Should we be able to obtain an additional power supply, we will announce the re-opening of registration on the FROG website.
