a very scorching hot july4 long weekend i am in burlington. wondering why isnt anyone in the water??

i dip my toe into lake ontario and found out why...ITS BLOODY FREEZING!!! i can understand the deep water being cold but not water only a few inches deep. rode ferry over to island for fireworks show. when show was over the buses and trains had stopped running. my sister in a panic having never been stranded in her life and i was sore from laughing so hard. TAXI!!
