People come, people go. I'll stay. I have the ability to read what I want
and not read what I don't want. Just because I'm not a whole lot interested
in the antenna stuff doesn't mean I'm gonna punish myself and miss the rest
of what I am interested in. Kinda dumb. This is a good list, off topic
sometimes, but so is everything. The local Safeway food store sells jumper
cables. So? Lee, K7INU
