I am planning to lease a horse and I'm really excited! I'll go to the stable for a ride three times a week on an adorable Thoroughbred mare and I've saved up the money. One problem: It's a 20 minute drive each time. How long it takes me to get there isn't the issue, but how much it will affect the environment. Unfortunately, there's no transit anywhere near the stables, so I'll have to find other ways to reduce my environmental footprint. Any ideas?
