My Dad's Thundereggs

My mom was busy cleaning out her back room.  In a drawer she found some of my Dad's old rocks.  When we were kids, one of our favorite things was to go rock hounding with my Mom and Dad.  She knew I would love to have a couple of these, so she surprised me and sent them to me!  This first one is a non-shiny one.  It feels like there are real plants in it:

This next one he polished up:

I always thought it was so magical to cut open these crusty looking things & find out how beautiful they are inside!  Thanks Mom!
