I think just a description of the nature of access would clarify. There's no marine access in Yukon, except for on the north slope, which is not accessible by road. So what we're talking about are essentially boat ramps in lakes and in some cases maybe a breakwater. So there is basically a gravel boat ramp or maybe some concrete lines down to water, typically installed at campgrounds or in a couple of small private marinas on rivers. That is the nature of them. They're relatively small and the amount of infrastructure needed to make sure they are safe is much less than what you need in a marine environment.
