I've been taking different routes to and from work trying to see if any one would be a better way to get home... I have one or two big obstacles depending on the scenario... The biggest is a swamp that is around 5- 15 miles in width depending on where I cross... the Power lines cross the swamp and have very little dry ground in the area... If we have a heavy rain the swamp can be as deep at 8 feet since most of the higher ground runs off into it... average depth is somewhere between 4 and 6 feet with occasional holes that will drop you deeper. I have a inner tube with a can of inflate a spare in my BOB that I can use. But my best guess ( I haven't tried to walk back yet) if I have to stay low key and skip all of the bridges is around 4-5 days to walk the 17-25 miles back from work (depending on route). My second obstacle is my health and age... I'm working on my health but I just seem to get older (not that I'm complaining). My question is if you were caught out of place at one of your normal away from home locations when TSHTF other than physical health and age what would be your biggest Obstacle getting home?
