Not sure how you would ruin things for other cyclists by stealth camping. The Katy Trail and similar bike paths are publicly owned, and there is not much anyone can do that would ruin it. As I see it, property owners are far better off having a bike trail through their property than a freight line, so they should be grateful and welcoming to people spending time and money in their area. Not saying stealth camping is OK, but that if it happens, it’s not the end of the world.
