Firearm carry on trails
It is always a good idea to have some kind of protection on trails from hostile people and wildlife. Just make sure you are legal and your weapon is legal. If you have a concealed carry permit, you can carry concealed in all state parks and now even in national parks. You can also carry loaded and chambered! Some people who don't like firearms may carry pepper spray or tasers, but I'm not sure on the legalities of carrying tasers concealed. I always carry my firearm with me whether on the trail or at the grocery store. Just make sure you are aware of postings on stores and know your laws and rights.
The difference between stupidity and ignorance. Ignorance is doing something wrong and not knowing better. Stupidity is knowing better, but doing it anyway. Don't be stupid!
