Wow, what a great story! The documented time-line is fascinating in itself. This is a perfect example of what and how this forum has grown to become a premier "go-to" source for pond info. To see Dr Dave in action some 3 years ago and still pumpin' it out today is inspirational; to link it to a specific project as this is historical evidence of his commitment and zeal. TyW33 is no less a participant; witness member #477 and maintenance of life on a thread that is 3 years old, yet only an infant in information. Congrats and thank you.
