Did you get them thru a baseball supplier? I have heard (but not tried them) you can get them from an artist/sculptor supplier for much much less money.
I don't think you should ever let them completly dry out. I would keem them damp by covering mound and batters box with a tarp when not in use, and sprinkle occasionally to keep them damp. Those are my thoughts.
When you block a person, they can no longer invite you to a private message or post to your profile wall. Replies and comments they make will be collapsed/hidden by default. Finally, you'll never receive email notifications about content they create or likes they designate for your content.
Note: if you proceed, you will no longer be following .
