1) All of the Fox Sports channels are available nationwide on major cable and satellite carriers if you simply upgrade to a higher-tier sports package.
2) If you are in an area with a crappy cable company, there are always two great alternatives. They are called DishNetwork and DirecTV.
3) Upgraded sports packages cost only around $10 per month and you only need to keep them for the months in which you watch games. So, if it's BYU football and basketball you care about, you only need the upgraded sports package from September to March--that's seven months.
4) If you already have cable/satellite TV, but are not willing to pony up a measly $70 a year to see your team on TV, anywhere, nationwide, you can't call yourself a real fan...my four season tickets to LES to watch crappy teams this last year cost me over $400.
