[TowerTalk] UST base grouting

Although my UST TX-455 is not grouted, it makes 
sense to me that it should be done simply to have 
moisture run off the top and keep the bolts a bit 
more rust free.  Here in the desert southwest 
that issue is perhaps not quite as significant as elsewhere.

I doubt much additional structural support would 
derive from grouting, given the 24,000 pounds of 
concrete in the base and a few pounds more of grout on top.

Thanks for reminding me, Julio - I need to get that done.
