If you are coming all the way from Philadelphia to get ginger ale and you want to buy a lot, you could always make a side trip from Charlotte to the plant in Cheraw SC. 74 is a pretty good road, at least until Monroe NC, stoplights thereafter. I wouldn't plan on making great time on 52. You should probably call ahead. I was there years ago and it was a shoestring operation. No doubt much improved since. Even if it did not work out at the plant, most stores in Marlboro Co. SC sell the stuff.

Was just in London for a few days. I enjoyed eating at Tas (High Street), Sheekey's, and Racine, and would go back. Rasa Samudra (Charlotte St.) and Fishbone, a fish and chips place (Cleveland St) were quite OK. Also OK was Ye old Cheshire Cheese, which I would go to again if close by at mealtime, tho I imagine it is a better place for a drink. The worst food was a salt beef sandwich at Sandowne racecourse. A pleasant surprise was discovering that McDonalds in the UK serves porridge.
