When I moved to Pgh in 2002, ramps were on every menu of every decent restaurant. I'd never heard of them back in New England, let alone ate one. Or garlic scapes, which I also love. Then again, I grew up in Stamford, not known for its farming.
The thing about ramps is that it takes about seven years for them to seed, so if wild ramps are foraged without leaving some behind to mature to seed, they could be gone in our lifetime. Of course there will be farm-grown ramps, but "wild ramps" has more appeal on a menu.
