Bridges and Running Water

[Douglas]

Do bridges over running water mitigate the threshold effect?  I'm thinking through some city design stuff for my hometown Ottawa and one of the major features is the Rideau Canal, which basically splits the city core in two, but there are a lot of bridges across it.  I'm still working on some of the lore surrounding the canal and it's construction, but I'm wondering how much of an obstacle it should be in the city's mystical environment.

In a similar vein, I wonder how magic holds up in Venice...

maybe venice is a nightmare to spellcasters...

I don't even know what types of water count.  The canal looks stagnant on the surface but actually moves pretty fast underneath.  In Venice it's sea water I think.  The last time I remember running water being used in the books was back in Death Masks, and Harry was immersed in it.

I imagine that standing on a bridge over slow moving water would represent a much lower threshold than, for instance, standing in a waterfall.

If bridges do mitigate the threshold then you would have to take other measures to maintain it's integrity. Like a ward or a guardian. Maybe that is why trolls set up shop under bridges.

Tidal waters complicate the matter as well. The strength of the threshold will change as the tide ebbs and flows. Slack tide would create brief windows of opportunity where the threshold goes to zero.

Perhaps the entire city is Accorded Neutral Territory? Like a supernatural Geneva?

Man, all this makes me think Venice would be a fun choice for a city to play in a game.
