How can I get my bacon less salty?
Soak and rinse... completely immerse the side of bacon for a few hours in clean, cold ice-water, drain, rinse, and repeat. A cooler is best for this, as it keeps the meat cool and offers lots of water for the salt to dilute into, otherwise a use a large pot in the fridge.

The downside is that this may also affect the "cure" - the smoke-flavor that many manufacturers add in lieu of actually smoking the bacon. Higher quality bacon may not have this issue (but then again, higher quality bacon won't be so salty).
