i agree with senior, mine have hit 80F last saturday(if you keep up with the motocross world, it was the same day a professional motocrosser died because of over heating here in michigan), but it was around 100F outside. I always keep a block of frozen RO in the freezer just in case this happens, when it did, i added the block of ice to drop temps.
I've always been told that crs and tigers will slowly die off after 76F.
