NANFA-- Texas opportunity (was East tx...)

I'll be introducing another group of neophytes (AKA members of our newest
class of Texas Master Naturalists) to the wonderful world of native fish (and
other aquatic critters) on Saturday, 21 September. This experience is part of
the regular training and will involve some sampling in the boardwalk area of
Lotus Marsh and the area just south of Eagle Mountain Dam (where our June
excursion caught the big gar and other species and unfortunately didn't see
any gators). If anyone will be in the area, feel free to tag along and help
(and hopefully learn). Just let me know so I can expect you.

(I hope to harass Dan into coming - he's such a hoot!!)
