I got a good introduction to polo in college when I joined the JV team for a few semesters. Unfortunately, I couldn't continue with it since my major had all of their tests on the same nights as polo practice and I would've missed probably 40% of the practices I'm still sad I couldn't spend more time on it, but I was at least to the level of knowing most of the rules and playing in intra-murals with the other players.
I recently started jumping lessons again at a farm owned by a polo player (my trainer just leases space). I see people exercising the ponies all the time when I'm there for my lessons and wanted to see if someone would be willing to give me a few lessons. I contacted the farm owner the other day and he's willing to give me some beginer polo lessons! Yay! I will never have enough money to own a string of ponies (I'll be lucky if I can buy one horse in my lifetime) but I'm so excited for the opportunity to learn more about this sport while riding someone else's lovely horses I even know of a local group that allows you to ride their horses in games for a fee (paid per season). I don't live close enough to join right now, but I'm hoping that I can improve my skills and join this club if I move closer to it in a few years.
