With a growing family of 5, three of those under the age of 5, I came to the stark realization that I could not survive with 1-2 bug out bags. Even if I was only accountable for myself, survival with one bug out bag would not be pleasant. It would truly be “survival” – on the cusp of perishing.
Therefore, I understood that I needed to have a better means of travel if I were in the unfortunate situation of bugging out on foot. Therefore, I’ve invested in a gear cart / sled. I found mine on auction for $20 and modified it further to accept bicycle saddle bags. You can find the link to this particular cart below, or look up a variety of “hunter sleds” or bicycle carts that you could purchase to do the same thing. There are also a multitude of DIY videos on making bicycle carts which may be of interest to you.
The main message is this – you need to try to carry as much gear as possible within reason. The cart/sled is the best way to do this. If for some reason you must leave the sled, then you can leave it and carry what is on your back. Point is, you at least had the opportunity to carry more gear by having the sled.
