Newsflash

Tuesday, May 15th at precisely 5:07 pm we will host our annual spring kickoff/fishing warm up/picnic. As in years past, we will be serving hamburgers, hot dogs, chips, desserts, and a few adult beverages. All are welcome and we hope to see old fishing friends from the other SE Michigan TU chapters. Location is Anchor Island at Meadowbrook Lake. Just South of Maple Rd, between Inkster and Telegraph Roads.
