Starting next week, I'll be hiking a section between Daleville, VA and Duncannon, PA. I expect the trip will take 5 weeks. I use an esbit stove,and I have a question for the experienced. Are esbit tablets easy to obtain in towns that might have a grocery store or convenience store but no outfitter? I have always bought my tablets at REI. Fortunately there is a store within walking distance of my house, so getting them has not been a problem. I just don't know how readily available they are. I'm not planning on mail drops, so that is not an option. My only options are buying them when I get into a town, or carrying enough for the whole trip. Help. Please.
