It's definitely my favorite fun fact. I'm grow up in the city but I spent a few summer days on a horse growing up. One of my earliest memories was horseback riding with my mom. I must have been no older than 18 months.
Note that you can also use the ranch business cards as 'get out of jail cards' to avoid social chatter when you need to change the subject: You note that the in-law starts taking the discussion towards some uncomfortable topic during thanksgiving dinner. You immediately use the card: "Say, have I given you my business card?" - and then you move on to talk about the ranch. Even if they interrupt you and try to get back to the topic, the topic will be derailed for good. Usable every 6 months by pretending that you forgot that you already gave them your business card...
My 16-year-old remembers a pediatrician's office she hasn't seen since she was 18 months old (we moved across the country). She described it well enough that her dad and I were both convinced. I was shocked.
