Volunteers remove thorny problem in Richland

Volunteers Dave Beach, Carol Berry and Merry Loew, from left, carry away trash cans filled with tack weed they scraped away Monday from the edges of the Sacagawea Heritage Trail near Wye Park in Richland.

They were on their third and final day of removing the puncture vine in the area on the paved trail popular with bicyclists and walkers.

The dried thorny tackweed seeds have a propensity for sticking into bicycle tires and shoes.
