So.... I stubbled across a web site... (http://www.moosemilers.org) that mentions a USATF Grand Prix Series in Maine.

The USATF Maine Gran Prix consists of 5 races.

May 14, 2006 - Portland Sea Dogs 5K (USATF Maine GP)
June 18, 2006 - Friendly's New England Mile (USATF Maine GP)
August 27, 2006 - L/A Bridge Run 5K (USATF Maine GP)
October 15, 2006 - Physical Therapy 8K (USATF Maine GP)
TBA - October, 2006 - Craig Cup 5K Cross Country (USATF Maine GP)

Thought I'd share... cause it's the first I heard of it!
