I bought a new Mnt bike this year with front & rear shocks just for this very reason.
I used my old non suspended one the last few seasons and at the end of a weeks hunt my rear was tore up[:'(].

The land whereI primarily hunt is flat and the fourwheeler trails allow me to glide along at a quick pace. The acorns on the road popping under the ties do make an odd noise though. BUTI have snuck up amazingly close to deer & other wild game while riding in.
If i down one I go to the truck and unload my quad for the dragging the deer back in chores.
The mountain bike is much quiter and stink free-I like it!
