I've always found the "can't cross running water" fascinating on some level. Depending on the geography of where a vampire was sired, that could be incredibly confining, or a huge swath of night in which to roam.
I mean where I live, I can see the Hudson River out of my windows to the east, about a mile north and south of me are sizable creeks that feed directly into the Hudson, and I'm not 100% sure how far west of me that I'd have to go to hit another north-south running water source but I can't imagine it's more than a couple of miles given that I'm in the Hudson valley and all.
Meanwhile, if a vampire were sired in say, Utah, you could probably throw a dart at the map and draw a Connecticut sized box around that dart to scale and not cross a river with the sides of that box.
And if we're counting plumbing and sewers as "running water" then unless the vampire rose somewhere where they still shit in a hole in the ground, they're practically imprisoned tighter than a fairy in a bottle already.
I think that's only using their own supernatural abilities to cross. So they would be able to use a boat. ---
