I'm new to this nice and clean town, but, that's all i know about it any insights ?

Watch out for radiation fallout.

From WIKIPEDIA:

ST. GEORGE NUCLEAR CONTAMINATION

On May 19, 1953, the United States government detonated the 32-kiloton (130 TJ) atomic bomb (nicknamed "Harry") at the Nevada Test Site. The bomb later gained the name "Dirty Harry" because of the tremendous amount of off-site fallout generated by the bomb.[12] Winds carried fallout 135 miles (220 km) to St. George, where residents reported "an oddly metallic sort of taste in the air."[13]

St. George received the brunt of the fallout of above-ground nuclear testing in the Yucca Flats/Nevada Test Site northwest of Las Vegas. Winds routinely carried the fallout of these tests directly through St. George and southern Utah. Marked increases in cancer and other radiation-related illnesses were recorded throughout the mid-1950's and early 1960's.
