The forecast at
http://www.onlineweather.com is much more promising, and is the one I normally rely on. It has ben quite accurate over the past few years.
Forecast for Edinburgh on Saturday is dry, Kinross has the chance of some showers later in the morning, but sunny intervals to start.
Regarding reserve slots - Paul (Shooooooomer) has been offered a slot, as a few people have dropped out. I'm currently waiting to hear back from someone who is 1st in the reserve list if he wants the slot, and there's potentially another (car not quite ready yet).
We still have 7 on the reserve list at the moment, but things always change in the day before an event. Will keep those on the reserve list updated with progress as it happens.
