Honestly, don't bother playing 4 or 5. They are in a thick, unkempt mess of cacti, weeds, mesquite, and the largest swarm of mosquitoes you've ever fought off in your life. 5 is near impossible to find and a guess at a crossroad to find. Luckily we guessed to the right which ended up being correct. My advice is to go from 3 to 6.
