I think that rather than doing less for boaters this more of a strategy for them to go to the government and say "Hey, look how great our charity and our infrastructure is for the health of the nation, something that you have pushed as a policy. Please give us huge financial support to ensure that these health-affirming facilities can be maintained and improved."
I don't know where most of the cash flow for CART comes from but I imagine a significant part of it is from licence payers, so I would also imagine that dumping boaters is the last thing they want to do. Perhaps I'm being naive but from by background working in charity and marketing, this looks to me more like an attempt to open more channels of income (which will benefit everyone in the long run) rather than a cynical attempt to dump the needs of the boaters. I mean, if they don't do what we want, such as - maintain tow-paths, uphold the natural beauty, make the cut navigable, etc - then why would anyone what to go for a jog or take their school class for a nature walk? Helping boaters is imperative for their business plan to work. Unless the just sell the land off to property developers ?
