Go to Old Mormon Fort in Freeside. Find Julie Farkes inside the Fort.
Choose the dialogue option to help them get medical supplies. Go through
the dialogue options to hear one that tells you that she just got a
shipment of magazines. Then, choose the "I have some medical supplies to
drop off" option. There will then be three options; choose the
"Rad-Away" option, as it is the easiest one of the three to find. You
only need to leave one thing if you do not care about fame. Every time
you give them something, you will gain more fame. After you give them
the supplies, choose the "I'd like to buy medical supplies" option.
There are a few aid supplies there that you can get if desired, but they
will not regenerate. In the supply list, you can find the magazines. Buy
any desired magazines, and then exit. You can then choose the option to
give med supplies again. This time you do not need to give them
anything; simply choose the "Never mind" option. Go back to "Buy medical
supplies", and you can repeat the process for more magazines. You repeat
this as many times as desired as long as you choose to drop off supplies
first. You can even come back to do it again at a later time. You can
get the following magazines: Fix-in' Things (Repair +10), Lad's Life
(Survival +10), Meeting People (Speech +10), Programmer's Digest
(Science +10), Salesman Weekly (Barter +10), and Today's Physician
(Medical -10).
