I have looked on the wiki, and I cant find Jacobs town anywhere, last snowglobe I need is there, where is it ?

About the dead left center of the map.

Look for the white circle on the left of the map with the road leading to it. It's at the end of the road.

Hmm always thought that was the nuclear test site. Well this is going to be a very long walk...
Thanks for the help.

... There arent any death claws along the way are there ?

no deathclaws just a lot of big horners.
