Free: Contests & Raffles.
The people at the bike shops are pretty into the sport and they're pretty damn helpful so that would be my recommendation.
For logging roads, a quality hardtail (no rear suspension) saves weight, complexity, and expense and will be just as comfortable. You may also want to consider 1x8 or 1x9 gearing with a small front chainring. You will sacrifice some top end speed but can still pedal at 15mph+ on flats or downhills. For hunting the objective is durability, simplicity, and light weight. Not every bike shop will have this combo but there is one fore sale on Seattle CL now in Bremerton for $350. I set up a dedicated hunting bike in this way and really like it.
You should look at a fat bike. I saved up and bought this one.
