Each year I've gone I checked the farmers almanac. It has been closer than the weather man. It said rain early in the week but warm/hot and dry the rest. The long range forecast is the one I check. The day by day is from the regular weather sources.
It will be just fine. So it rains a little. My MINI has windshield wipers. It's the rock slides that worry me.
Working on the functional prototype today, actually. Should be done tomorrow. Not pretty, but should be functional.
