I used to live on Lake Livingston years ago but now I'm near Dallas. Thanks for posting about this maybe it will help someone else locate the minnows in that area.
LeRoys bait & Tackle on hwy 78 west of the East Fork on the left hand side. Open until 9:00pm during the week & 10:00pm Fri/Sat.(972) 442-5090 ask for Brenda she`s a very nice lady.
Yea they charge 3 dollars per dozen. Not sure if that's is the usual going rate. There was another gas station there in Princeton down 982 that sells them and they charge 3.29 a dozen.
Yea we used to buy them right at triple creek marina when my dad lived there and I think they were only 1.50 a dozen but this was probably 15-20 yrs ago.
