First and foremost: the muggle situation here is such that I
suggest that you do NOT attempt this cache during normal working
hours, 8-5 on weekdays. Evenings and weekends should be much, much
better.
Cache is a large camo-painted plastic screw-top jar with room
for travel bugs. Although a multi, this cache should be very quick
-- essentially a drive-by. It's also very convenient to I-10,
perfect for that geocacher just passin' through.
The coords above will bring you to the middle of a road. The
house on the east side of the road was designed by Frank Lloyd
Wright.
Now, I don't happen to be a fan of Frank Lloyd Wright -- in
fact, I think he was a lousy architect. But there's no denying his
fame (helped by Simon and Garfunkle) and there's no denying that
his designs are distinctive. I'm sure many geocachers would like
the opportunity to look at his work.
It's private property, though -- you'll need to look from the
road. You can drive farther south and around a bend and get a look
from another angle if you wish.
I'm betting that, when this house was built, it had a commanding
view of Lake Jackson. Now there's an entire neighborhood built on
the flats, and you can't even see Lake Jackson from here.
To get to the cache itself: The address to the Wright house is a
4-digit number right there on the mailbox. Add 6169 to this number
and use the resulting 4-digit number as the last four digits of the
latitude: N 30° 2X.XXX. Add 5670 to the same 4-digit address to
obtain the last four digits of the longitude: W 084° 1X.XXX.
