You mention getting home...which is my plan ... shelter in place.
I realized I would need a great deal to get there...across a river to a barrier Island. Causeways will be closed!
I call it my GO-BACK BAG and it is stowed under the top level of trunk in car. Inflatable, paddle, flippers, life jacket, clothing, water and snacks...on and on and matching jacket for the dog too.
I thought I was prepared and then one day it hit me...GET BACK??
I call mine a return home kit/s. I take them with me when ever I go over 5 miles away from home. I figure it will take me longer than a day to travel over 5 miles to get home. So I have just about everything I would need [including a portable shelter [read as a tarp] & several hundred feet of 550 cord, amongst a bunch of other items including meds for a week or more.
This looks real good.
My commutes are very challenging, I spoke about them on my youtube channel (I shut it down because it was affecting business).
My commute from PA to CT was full of strange challenges.. mostly legal. But a large state forest and national park were between my house and work. So my car, even today, has a 72 hour bag in the trunk.
Way, way over kill. But it’s what is needed. I can tell you this though - I’m not sure if your water way is important (I’m thinking Galveston is important) but there are laser scanners that skim the tops of water in places like Galveston. Boats aren’t that good of an idea in places like that.
If you send me a private message with that location, I can offer a more targeted analysis.
There are always ways of getting over water.
