Sorry for the stale data.
SC gas supply - had lines yesterday, seems better this morning. Saw one station raising the price from $2.45 to $2.99 for regular.
Aside from gas, if you'd like a good example of a supply and demand market, watch the prices on plywood, lumber and shingles in the next 6 months. It could also affect the money market, if enough people borrow money to repair/replace their homes. Harder to guess that one, though.
Gas mileage: noted the Boxster 20-21 mpg figures in another thread. It's about what I get, except for the track. I burned almost a tank in 3 runs, but as Tom cruise once said, sometimes you just gotta say "WTF".
