From Mopac Go north on Highway 183. Take the McNeil/Spicewood Springs exit. Turn right (east) on McNeil, you will see Jack in the Box and Walgreens on the corner (by the big, light blue water tower). You will pass the Water Tank Restaurant and Bar on the right. The first light is San Felipe (look for Jack in the Box on the left). Turn left (north) onto San Felipe, you will see Tin Star Restaurant on the left. Summit Creek is then the 2nd community on the right.
