Three weeks might be considered much by some, I guess.... I usually
try to get four each summer, but due to the SE asia trip this spring
.... three was all I could get out of the PHB:-):-)

Been "tapped" by the PHB, a retiring DBA, a few programmers some
windoze admins and some few users(!)... That and the raining and the
usual repairs on the house (painting the awnings (I think that's the
right word for that particular part of the roof:-)... A lot of
climbing around, which isn't as easy as it used to be:-)... Not much
of a vacation....:-).
VPN is the death of relaxation and recreation.... You know how it is.
