In reference to talk of spending hours and hours on a coat, I can't claim to have done that...Mingus sheds out slick and shiny no matter what I do, so the brushing we do takes no more time then you would with any horse. He loves to roll and typically looks like a powdered doughnut, so if I want to see my shiny horse, I have to brush!
Capall Beag, I run my own business, play music semi-professionally in a jazz trio and other groups, am a manic gardener, read voraciously, have many interests, work in animal rescue and take care of 4 dogs and 3 cats, have started getting back into trail riding, and in general have a very, very busy life. The time we spend in show prep is time we always spend with our horses, only now it is more focused. Just as with your kids, a small amount of time focused specifically on them is worth hours where they have only your half attention.
The funny things is, before every show we've entered, my business has gotten extremely busy, keeping me from putting in as much time as I wanted, so the daily work, even if for a short time, has really paid off. Now if I could just find a way not to be scrambling at 2 am the night before just to get everything packed, I'd be happy!
