Do not drive down to the ramp at 'A' section unless you are rigged. No inflating, loading boat and etc. allowed on the ramp. You get about 5 minutes to unload and move all your gear off to the side of ramp where you can tie up and finish packing boat. The only required gear is a groover if going past 'A' section and life jackets.
I have ran it as low as 850 (pack light, no cast iron), gets boney at red creek rapids and up to 4,000 with no problems at all. At 4,000 the fishing gets tough.
Time is like a river. You cannot touch the water twice, because the flow that has passed will never pass again. Enjoy every moment of life on or off the river.
