Hi Zeke: While your in the Chlt area a stop at the newly open NASCAR HOF will cost you $20.00, but it's A/C will save you from the heat for at least 4 hours.Thats how long it took for me and my family to wander about looking at some very intresting artifacts.
Even if your not a race fan, a stop at MWR in Huntersville can entertain you with there "FAN ZONE".A clear view from the second floor of ALL SHOP ACTIVITES, might even get lucky with drivers in house?
Another Museum stop is located in nearby Mooresville NC.Many more race cars than at HOF and half the price."MemoryLane Museum" Hwy 150(River road) just west of exit #36 on the left, you can't miss the huge 2 story building crammed full.
Spencer,NC has the Transportation Museum highlighting TRAINS but also a peek at a few vintage cars and trucks from back in the day.Well restored for public display.
No matter your stay drive carefully and be sure to bring your camera.Your bound to like something we have here in NC.
