Get a plow for Mr. Smith

Introduction
In Vault City, behind the Cassidy's bar and the Dr. Andrew's Clinic with the half working Auto-Doc, there is a stagnant family with the resources neither to leave this town, nor to earn their sustenance.

Steps
Speak to Mr. Smith in the outskirts of Vault City behind Cassidy's bar. He redirects you to "Happy Harry's" Shop, in front ot the Clinic, to ask for a plow. You can buy it for $800, but a decent Speech (more than 50%) skill can lower it to $600.

Rewards
Return the plow to Mr. Smith for a Desert Eagle .44 and 250 XP.
