Ok, so you pack and carry a tent and a seeping bag just in case .... and when you go on a day hike?
What do you carry when you go on a backpacking trip? A generator and a fridge .... ?
Yup, but only in areas I am permitted to bring my wheelbarrow.
In all seriousness, I do carry windproof matches, a lighter, and paracord that is also intended for use as a firestarter whenever there is a chance that an injury will keep me in the woods for the night.
That also being said, if I am hiking in remote areas I definitely try and bring enough clothing to live through the night as I know how much work and mobility keeping a fire going takes to keep me warm and the most likely scenario for.me to get stuck out overnight is a lower leg injury... but ya, I always carry fire making stuff because it is light and you never know.
