Well I know most people will have issues going out alone and especially at night. I was pretty much the same way until I joined the Army and then pretty much most of our training and missions were done at night, even during peace time in the early-mid 1990's. I ended up getting used to it but if someone isn't used to it, your senses pretty much take over, the adrenaline kicks in, and you hear every little noise and your eyes are wide open so you can hopefully see your surroundings.
It takes a little getting used to, but also with todays times, you got meth labs in the remote forest mountains, you got possible criminals, drug dealers/gun runners, depending on which part of the country you are in.
Fact is I have no problems going anywhere alone, day or night but you can certainly bet I carry a semi auto pistol, with 4 full mags and a full box of ammo, and also a 6inch blade knife and a machette, (both of which I keep sharp enough to shave with!), if I am planning on going out to a remote location all alone.
If anyone plans on going out alone in any area whether it be their first time or experienced. Better make sure you have supplies for any senerio. I always carry a 9 volt battery and some 0000 steel wool and a can of WD-40 of I need to start a fire. This is just 2 main items I bring with the rest of my supplies. The 9 volt battery with 0000 steel wool, tear of a piece of wool, make contact with the 9 volt battery, once red, put it in some kindlings and get a fire started. The can of WD-40, (of course you have to be REAL CAREFUL WITH THIS ONE), this is in case you get caught in a rain or thundersorm and have wet wood, but no fire!
Get your wet wood piled up, with some wet kindling, spray the WD-40 at the bottom of the wood and kindlings, light the spray with a lighter and flame the wood. The wood will eventually catch, (usually using about 1/4 of the can just depends on how wet the wood is), and once it gets going it will dry out the wood and you still have a fire going. Did this several times and at our gold prospecting outing. It rained like a dickens and the club president was trying to get a fire started for about 30 minutes before I came along, even using gasloine and couldn't get it going because the wood was too soaked with water. I got the WD-40, lit the spray, sprayed the flame spray at the bottom of the wood, it disipitated the water out of the wood causing it to burn. 5 minutes later we had a good fire going!
But besides that, always before you go out into the wilderness, get maps of the area if you can, look at google earth before you leave so at least you know what is around, water source, population, etc. But mainly research your surroundings on what type of wild animals and preditors are around and ALWAYS bring a first aid kit! Many people will never think of bringing one, and don't leave it in the veihicle while you wonder off!
