Thanks, Kelly. Just to be sure I am posting a couple more pictures. Albloggerque gives full-screen enlargements, so click on the pix and check it out.
The top picture shows Bob Evans and the whole plant. Actually, the plant seems to grow low to the ground and is bigger than the frame of the photo.

The last picture shows those boogers with my sunglasses in back of them for size comparison.
What do you all think? Is this jimson weed? Yikes.
