For those who need a bit of help, the supplies needed from Jonestown to Union city is 6. The route I took was 'Whispering'(the bow is awesome), and with surplus of 2 supplies to aspenwood (you should leave when you have enough to reach jonestown +2,3), one night in jonestown (Use your first night to search the apartments and stores with '$' signs on em, they hold the most supplies. With luck, you'll get 2-5 supplies with a full 12 hour search.) and then union :) Hope this helps!
