I used to ride, and my son did a lot, but I kept breaking things so I took to driving horses and loved that. Alas, where I am now I only have an acre and that's mostly garden and orchard so no horses at the moment!
'Black Purse', and the book 'Oginalli' sound very interesting, the second one especially for me. I hope that in three months I will get the chance to read them. It sounds like you have a unique 'voice' in your writing and that's a blessing. You don't get lost in the crowd!
