trickey280 is correct. It is a pretty small town...but it does have some nice places. You are only about 20min to the North Unit of the Theodore Roosevelt Natl Park (if you are into outdoors)...not too far from Lake Sakakawea (to the north) 45min. from Williston (not a huge town, but has the basics you need). Watford has a good school system, new playpark, theater, Bar&Grill, and are now working on a new Health Center. Pretty decent little main street...couple restaraunts, few bars, grocery store, the basics. Summers are VERY nice in North Dakota...not the Hot HUMID summers you experience back in Pennsylvania...dry heat in North Dakota...but it does get hot in July-August. Housing is an issue...so prices are a little overpriced because of supply-demand going on with the oil boom. Make sure you have housing lined up before you come up...it is nearly impossible to find housing. But many "man camps" are being built in the Williston-Watford-Tioga-Stanley areas...I know a couple new mobile home parks are being built in Watford City as well.
Below are a couple links to Watford City that might be helpful...their local newspaper and official town web site. Good Luck!
