I went on an 'old fashioned' camping trip. Nothing but rider's their horses and whatever fit behind the saddle/on the horn. The place we went didn't have accommodations for horses so the horses were either tied to trees or hobbled. It was a real roughing it place with nothing but dirt sites, fireplaces and parking at the front for your trailer and car. No vehicles are allowed further than the main entrance so it's all walking or horseback. I wasn't intending on going but someone called me a 'girly girl' and and 'dainty little princess' before they told me I couldn't hack it camping 'like real men' so I had to go and prove them wrong. I don't think I've ever been clapped on the back or high fived that much in my entire life, but they were thoroughly impressed with how a princess and and old fart of a horse held up, and although I'm not fond of not having a functioning toilet, we are offically invited on all 'man trips' in the future. We rode 104.3 miles during the trip which was really nothing for a week long trip but they wanted to sit around doing 'man things' that I couldn't possible have begun to understand. Looked like sitting around being lazy if you ask me but then again I'm not a man.
I'm wishing the best for you and Biscuit. Hopefully it's good news from the doctor and you can get back in the saddle. I'm sure that will help with the timid and spookiness. Probably just needs some normality back in his life.
