Last year I visited the city of Barranquilla, Colombia during the months of Carnival. I observed all of the costumes along the parade, enjoyed many interesting things and learned about their cultures. I went out with my friends; no one danced or played at the festivals, but I enjoyed it and always thought about having fun. One night, I was drinking vodka and the rest of the group was sent to the hotels. I had fun and sang all throughout my journey.
1- all of the costumes along the parade
2- and learned about their cultures
I know it should be singular, since Barranquilla must not have more than one culture, but in the original is into plural, so you should translate the way it is, ok?
