Floodwater is no laughing matter. I'm guessing your area is pretty flat so hopefully the water ain't fast. Around here with the hills and valleys water can gain a lot of velocity. But most of my route home is mostly rolling, not a lot deep valleys. If bridges are out I have a some marina areas that I would hope to scarf a canoe or kayak to borrow. My direction home would help with that. Going the opposite way would be much more sparce for options.
