Description

I think this is an invasive weed growing in the middle of an old logging road.

This old logging road on prospect ridge was destroyed for hiking and straw was brought in to reduce erosion but it brought it lots of weeds too. How ironic.

I wish they would turn these old roads into trails instead of digging them up and making them difficult to hike
