I just sat and bobbed for 3 hrs today

OK the wind was forcast to improve and blow 15 knots this afternoon on Lake Huron.... but it didn't it died... the first 2 hours were kinda fun, almost a challenge... but the last hour seemed to take forever. Then I started to hear thunder... a squall line came up and almost flipped me.... I couldnt even go into shore i I had to sit in "irons for 15 minutes until the wind calmed down a bit... it was a tough day on the lake
