America has beautiful places, cultures and land to visit. No need to go abroad.
And where in "America" have you visited?
I agree that the United States has a lot to offer. I'm assuming that by America you mean the United States. I've been to most states in the US, traveled through Canada a few times, drove to Alaska. North America is my home, and I've enjoyed it tremendously.
In 1968 I traveled outside the US for the first time. I want to Mexico and, for brevity sake, won't go into all that I did there. I lived in Mexico for about six months, had an apartment in San Miguel de Allende, and traveled through many parts of the counry, often on "chicken buses." My time in Mexico was a wonderful, eye-opening experience. The people I met were warm, friendly, and helpful, and the places I visited opened my eyes to seeing things in a way I never experiened in the US (until that time).
As beautiful and culture-rich as America is, it's but a small, and rather insulated, part of the world.
Latin America became a place I visited somewhat often: Ecuador, Peru, Chile, a taste of Bolivia, and a stint in BA, also Panama.
I've enjoyed wonderful relationshps with Latinas from Colombia, Panama, Peru, and Argentina.
My regret, if I really have a regret, is that I didn't travel more. I think not experiencing Italy would be that regret.
