Well two days to go, and everything is still on. A couple of points:
1) long range weather forecast is 30% chance of showers early in the day, but clearing through the afternoon and sunny into Sunday. A few clouds in the sky on Sat. Afternoon, IMO, makes for better landscapes than a perfectly clear sky as predicted Sunday ( I hope )
2) highs for the day are only predicted at 12-14C or around 55F. However there is always a cool breeze off the lake, and it always feels colder than it really is, at any season, so bring an extra jacket or sweatshirt or sweater or whatever.
I'll have my 4x5 setup in the small park beside the lift bridge.
