RE: bicycles
yes do it. here in north idaho there are thousands of closed roads. we ride our mtn bikes in 10 miles to get to our elk huntin spot. once there you can usually hunt alone since most people arnt willing to walk that far as far as gettin out your game once youve killed i rope 2 quarters on my bike just like you would with a horse then walk your bike it works way better then a packboard good luck
