It's totally safe, you just have to be an educated traveler and know the "rough areas" to stay away from. You're totally fine in the US as long as you avoid: major cities, urban areas, suburban areas, rural areas, universities, high schools, schools in general,  any roads, sporting events, concerts, churches, museums, restaraunts, etc... National Parks are safe except during hunting seasons. Inside airports are generally safe! Enjoy your visit, we'll be happy to shoot you around!
