what is a ramp?

[larryours]

GoodOlBoy, if you keep on about what the h@*% is a ramp, I might have to send you a pint jar of my pickled ramps( after I get back from my bear hunt) After they are pickled they don't have as much a lingering smell, but they are da*'@ good with any meat or cold cut sandwiches, you will have to leave me a mailing address. I'll have to double bubble wrap them, they could be consider hazardous materials
