Thanks for the replies - I'll definitely try it again next time I visit Austin. The good/bad news with Austin is there are alot of other things to do their besides fishing. Once I finish up all the touristy stuff, I'll be more apt to sweat it out for an entire weekend. That said.... 5hrs of driving to fish 8 hours without a bite will put a hurt on ya.
TXMulti-Species, Glad it's been tough for the folks who know what they're doing too. I had myself believing LBL was going to have the fish keeping me busy all day.
Instead I got served another meal of Humble Pie!
Sidenote - If you're in Austin and want a good burger. I highly recommend Casino El Camino. The place is a bit "unique" for aesthetics, but a great burger!
