Don't Touch This Weed!

Wild parsnip (Pastinaca sativa) plants are rising towards their full height and blooms are beginning to appear in southern Ohio.

  I learn from you so much about living in the moment, talked to me about your hitchhiking [the old days] and how you think it’s fun to run out of gas. These moments that others would consider worrisome are...
