Agin whil i travel i would try to keep to the river until the next town. Once in another town i would slowly look for survivers. If the day turns night while im searching id return to my boat and anchor off in the middle of the river making sure that i wont move id then rest and continue my search in the morning. But for the most part if i dont find anybody my plan would stay consistant. And yeah if the number of zombies didnt increase in my first area i would be content on staying there until supplys ran out. Then i would move on. also in my time in my house i would work out my legs so that i can move quicker during my travels if it came to it.
