Hmmmm. Terry, it looks like you were able to post your picture in the PDB. It may be that Dave has diabled the ability to post photos within the threads of this forum. But that's a little odd, so I'll see what I can find out.
Molly, I ended up combining a couple of Yucca entries that were synonyms; in the process your image got moved (the link above goes to its new "home" now.) But can you re-add your ZIP code on this entry?
