I was uneasy about sending stuff for WB3 to a business but believe I've found his mailing address. I'm uncomfortable posting it on open forum but if you'll PM me... I'll give you the addy I have.
I sent a little money to the steakhouse where the Celebration of Life was held. Today I received a very nice thank you card from his kids. The card had a pic of one of Willowbilly's art projects on it. An excellent remembrance for a truly unique friend.
So, if any of you send a sympathy card, it should get to his family.
