Just wanted to post a little more info about my previous post. It seems to me that there is a bit of a misconception out there that guides make a ton of coin based on the rates that they charge, but I don't think that's the case. I've looked into doing some guiding myself, and it costs a lot of money to run a boat on the river. The guide has to pay for fuel, both for the boat and towing the boat to where ever he is launching. He has the insurance on the trailer, and on the boat. He has to pay for gear, lunch for the guests (usually), maintenance on the boat. I would say it's safe to assume that most guys are making payments on their boats as well. So, saying all of this, you need to factor all this into the cost of the trip. Like I said before, ive looked into doing a little guiding. From what I can figure, you need to do lots of trips every season to make a living, never mind a good living. So why not give the guy a little extra for his efforts. If it's not in the budget, no problem. Just let him know that it wasn't anything that he did wrong. If you can afford it, use your own discretion. Whatever you feel is appropriate if great.
