My wife and I took a day trip yesterday from South Richmond, VA (Chester) to Danville, VA. I was fully charged and left Home with a 307 mile charge. The trip was 152 miles to Danville with about 30 miles around town. I knew the trip to Danville and back to South Hill to supercharge was around 250 miles. We stopped in South Hill and supercharged back to 307 miles. The supercharger is about two miles off I-85 in a remote location. Very difficult to find for a first timer. Regardless, any supercharging is wonderful. Just to be safe, we stopped on the way back for 36 miles to ensure no problems getting home. Would have made it with 14 miles to spare without, but with more experience, I'll trust the GPS more. Always fun to bond with other Tesla owners and share your Tesla experience.
