On our recent trip to Inskip I to kept watching the long range weather report & it didn't look good. We got wet on the trip there & copped a few sprinkles on the way home but the entire time we were there it was absolutely perfect. Sometimes I think you just have to take a chance & if it is overcast or does rain it is usually a bit warmer anyway.
We are to Canungra in two weeks & I'm expecting it to be freezing then but I am still looking forward to it. Like you I am worried it will rain but it won't stop me, might just mean I spend most of the time under the blankets in bed reading
