edit: It isn't the same, but in Michigan, all navigable water is a public right of way. I would assume similar rules exist in other states.

There was a neat corner case with easements/rights-of-way and water from property class that I would constantly screw up in hypos. I obviously bombed it on the final but whenever I hear it I always think it is interesting. I think it is something to do with waterfront access to property that is otherwise inaccessible.

Possibly the situation where a public resource or right of way (eg. a lake) is completely enclosed by private properties (eg. a developer or HOA acquiring all lots which have any of the lake's shoreline)?
