Sorry Britt, I only just saw your question!
I've only ever heard of one type of MG,
But your pics look the same as what I do, So I suppose english?
Australia is hosting the MGA worlds this year,
I'm so excited!
I wish I was good enough to make our team, but alas i'm not.
It's going to be awesome to watch though!
I could never afford to get seriously into horses when I was younger so I never joined pony club or anything (that's mostly where people do mounted games in the UK) and never had my own horse. I really wish I could have done it though! Bit to old now...
