The backcountry could be closer than you think. In the early half of the 1900's there were hundreds, if not thousands, of ski areas peppering all of North America that don't exist anymore for one reason or another. There are organizations out there that keep detailed records of each one of these places. You may realize that there are perfectly good bumps right under your nose. Since I live in New England, I use www.nelsap.org to find hills in my area. Back country is a great way to get more out of your day. Bring the dog and some snacks on a blue bird day and enjoy nature the way it was intended. It's a different experience when you aren't always seeing nature at 60 MPH.
The question is, how do you want to get there? Do you want to take the cheap way out and snowmobile to your destination or do you want to snowshoe or split board to your spot of choice? My vote is to use a split board and there are plenty of people on the internet who would love to show you how it's done. Here's a great article that explains what it takes.
