54.... no way. We rode 2 weeks ago and it was 61 on Sunday. Weather was in the 80's all last week and weekend. I'd be willing to bet it's close to the 70's. Not sure how long it'll stay that warm for, though. Looks like we'll be cooling down in the next couple days.
When we rode Sunday the water registered 64 on the PP. That was constant throughout the day from railroad to Turners cut. We trunked it with a top and was more then tolerable.
