I am from Mexico, and I've been to the US 5 times:
In the first time I went on a road trip all the way from Guadalajara, my city, all the way to McAllen, Texas. I went there with my parents, uncles and aunts, grandparents and cousins. It was very fun for me, as it was the first time I ever left my country. After that, we went to San Antonio. I really loved to experience a colder winter weather than I'm used to (in my city, mornings are below freezing, but the same afternoons are like 20 C? (68 F?)) and see some leaveless trees. As I was probably 7yo I don't remember much, except for taking a walk around the river and spending new year's eve with my family, and going to the fair.
My second time in the US I went to Chicago, Illinois on airplane, on April. It was really fun, I visited the aquarium and other museums, the people were nice, the food was great and my overall experience was the best. We took a boat on the Michigan Lake, and we went to Navy Pier.
On third time in the US, I went to California and Nevada. We flew to Tijuana, and then we took a bus to LA, where we went to Hollywood, Disneyland and Universal Studios. We also visited a lot of other places as well. After that, we went to Las Vegas. I dont remember, but I guess this one was on April as well.
My fourth time was on Oregon. I took an airplane to Portland, but just me, alone. My uncle and my aunt picked me up there, where I went on a week-long summer camp, which I loved. The people were super nice, and I really loved the nature. We did lots of activities like hiking, fishing, swimming and canoeing. After that, my uncle took me on a tour around the OSU, and we went to Newport (where I actually swam in the sea (it was really cold tho) and Salem. It was really fun.
My fifth and last time in the US, was on July, two years ago. We went to Oregon as well, but this time with all my family. This time, we went to all those places I had mentioned, but also to Crater Lake, and some other parks, mountains, lakes, rivers and waterfalls, which I cannot recall. The only one I can recall are the Multnomah Falls.
