thx. But i kinda ment sayy if he was at megaton how many days would it take for him to come back
to megaton.
Does not matter the location. All traders will cycle through in two hour increments. Wait outside of Megaton, set the timer for two hours and a different trader will show up. I think Wolfgang is after Harith, but does not matter. If you do not see a trader, be alarmed and talk to Roe. A trader can die, usually out side Canterbury, Arefu, Megaton. The safest spot is River city, plus you have the locker to store stuff, but you can drop stuff on the ground and it never goes away or is stolen, just remember where you dropped it. Hope this helps. Good luck.
