The title piqued my interest: 10 Shameless Ways To Eat For Free. Bob's philosophy is that nothing in life is free. Sure you get a "free" breakfast at some hotel chains and B&Bs but let's be realistic. The cost of breakfast is part of your room rate.
We've even stayed in some hotels that offer an afternoon happy hour with a free drink and appetizers or a sampling of a local restaurant's offerings. The Hampton Inn in Fernandina Beach on Amelia Island in Florida offers a "Chef's Taste" with a sampling from a different restaurant each night.
The article on SmarterTravel started out with something I'd never heard of before--freegan. Basically it involves dumpster diving outside a restaurant or grocery store. Sure. That's what I want to do. Get my meal from a dumpster. Apparently there are those other than the homeless or down-on-their-luck who do. There's even supposed to be an app for it. I looked in the app store for it (Leftover Swap) but couldn't find it.
Since dumpster diving could get you into some trouble--the dumpster is technically private property and you could be accused of stealing, there is an alternative: foraging. And yes, there's an app for that and I found it. It's called Wild Edibles Forage. Lots of pictures and description and location. Anyone remember Euell Gibbons? He knew all the edible parts of a pine tree. This app was created by "Wildman" Steve Brill, a naturalist, environmental educator and author who gained notoriety in 1986 when he got arrested in New York City for eating a dandelion in Central Park. So I guess even foraging can get you in trouble. I'll stick with the "free" breakfast, happy hour, and a good dinner in a restaurant.
