Honestly? This goes hand in hand with what I said in the other thread about charity rides and runs.

If it's really a fundraiser, then it should cost more than it costs them to put it on. A lot more. And it should cost more than the ride alone is worth to you.

Now, just because it's pricey doesn't mean the money is going where they say it is, obviously. If the Rotary is an organization you want to support - or the particular chapter who's putting this on - ask for the financials for this ride, and what projects it will be used to fund. If they refuse, or if the numbers don't look good, then there's your decision.
