Homeschooling is definitely an option. On a practical level, nowadays there are tons and tons of resources easily available for pretty much any approach to homeschooling, vastly more than ~20 years ago when we started. The time spent together makes for strong family bonds, both among the kids and between parents and kids.
Speaking as a homeschooler, the middle of nowhere can be a plus and a minus for homeschooling. Rural life offers opportunities that are much less accessible to (sub)urbanites: agriculture, animal husbandry, large-scale building/craft projects, homesteading skills, etc. On the minus side, other opportunities may be non-existent or may require lots of driving: libraries, music lessons, homeschool co-ops, sports (formal teams or general activities like swimming or skating), community theater, mentors for various interests.
So don't rule rural life out on educational grounds, but as others have said, I'd still only choose it if I wanted the benefits of rural life.
