It's not a good idea, it's a great idea! I rowed my 12.5 foot cat down it a few weeks ago at around 750cfs, I wouldn't want to do it any lower, but it was a good time. It's a good idea to scout 2nd Mud slide and the Eye of the Needle. The road is still closed, but hopefully it will open this weekend kind of doubtful with a storm coming in tonight. It took us around 7 hours to run the upper and lower boxes with 3 rafts. There are some good rapids in the upper box, (Lone Pine, Limestone) but it makes for a long day.
