"Never Mind. I gave up and uninstalled TBC once again and also deleted practically everything "Trimble" then reinstalled TBC. It works now. The rest will have to be installed again later. JAC"

"If life were perfect, we would all paint, we would all play an instrument, we would all dance. But because we know that life isn’t always perfect, we have to have dance, we have to have music, to remind us how good life can be." – Suzanne Farrell

I love the days that you sweep through here and straighten everyone out... you truly are an inspiration Mr. Cavell.  The surveying world sure is lucky that you chose it as your profession.

Hi Mr. Cavell,  Just want to say hi,I have work in LA.a few times.  Most of the time was on the Mississippi River for the Corps. of Eng. , but in 1978,1979 i did a dredging project on the G I W W.on the Grand River,Bayou Sorrel,Bayou Grosse Tete and Bayou Plaquemine , and i live in Plaquemine.  SO not to far of Stick Red. I enjoyed the time i spent there and even had a peroy made for me, love that boat.and saw the largest cotton mouths, one was big as a Dragon. Any way just wanted to say hi and you have a good day sir. Thank you for your time.

Billy Brooks
