Hi Steve,
That was next on my list. Honestly, I'm getting tired of driving around with
zero results and dumb looks by clerks/staff. While I could phone ahead to some
of the places, getting somebody knowledgeable has, in the past, proven to be
somewhat of an "experience".
The materials I listed I've in the garage and I could assemble them in little
time. I'm hoping that Bob will look favorably at my approach and maybe help
somebody else that may be in the same situation as me. If not, that's Ok, too.
Then on to "Plan B" - whatever that might be. ;)
Thanks,
/\/elson
