It made me think of my mom and miss her a lot ... she loves cactus gardens . Rafa and I spent the rest of the day at the beach . Friday night , I have to say , was the highlight of my time in Rio . Sure the beaches are nice , the city is funky , and the views are spectacular ... but there is something else that Rio is known for that I had not yet experienced .
