mine is a 20 minute drive however im moving this sunday to a yard which is about a 5 minute drive so that when its snowing like it is now i can walk there as it's so difficult at the moment :/
5 miles by car = 10 minute drive slightly less as the crow flies.
For a year I kept him at a livery 20miles away and I would never do this again. I hated it. I would drive up there on a cold night, nobody was there when I got there and then would give kiss and carrot and drive 20miles home. Last straw was when he had colic luckily mild and the YO left me to it and didn't offer to do a late night check. Now he is near enough that I can do it if need be.
