I would reccomend getting a guide as well. I know that it is a run that most people are very familiar with, but I have had several days on that water that were less than enjoyable. It is probably hard to get someone to run it in the middle of the week, but definitely worth the wait. It it one of the better runs that can be hit in the off season, so make sure you learn it!
The cynic knows the price of everything, but the value of nothing!
