Hi, I am putting together a collection of hollow geodes if possible, atleast geodes/thundereggs/Agates from as many states as can be found. I post on the rockhound site McRocks, and have a post about this project on there now.With this project I plan to show a cut one and an uncut one from as many states as possible. We will get this posted on the McRocks board for all to see.If you can help with a couple from your area,,Please let me know. Thanks, Rick.... keep4u@yahoo.com
