Ft. Pearce is in the Warner Valley and has weather (WX) much like St. Geo. There is a light bloom from St. Geo. but if the atmosphere is clear it is not too bad. Personally, I'd stay on the dirt road and not turn towards Ft. Pearce. That way you remain on the E. side of the valley along the Hurricane Cliffs. Plenty of places to pull over on short side roads. Use one of the hills to the W to act as a light shield. Astrodeb may be out that way that weekend as well. Our house is in Cliffdwellers (917 W 3450 S) please stop by and say hello.
