In the morning I take the car so it takes about a minute to get my pants on and get down there... In the afternoon I walk so it takes about 2 minutes.
When I was taking lessons I would haul about an hour. I have boarded in the past and I've kept him as far as 45 minutes away without being conveniently close to anything. It would definitely be better for you if it was on the way to or from work or school. It gets hard to get out there when it's a special trip.
My horses live about 7 miles or 10 minutes away from my house. They live on my grandparent's property and my husband and I rent an apartment nearby. My horses and I have moved a few times over the years but my horses have always lived about 10-25 minutes away from where I live.
My barn is 2.3 miles from my house. It takes about 10 minutes to get there, because it's all back roads (30mph) and the last half of it is on a dirt road, which I can't drive very fast on because of my little old car (1986 Ford Escort GT).
My old barn was 13 miles from my house and took 20-25 minutes to get to because most of it was highway (50mph).
