A very good attempt, qednick, and other than the obligatory "IANAL" disclaimer on the front, it seems fairly complete.
I do have one suggestion, that you review the terms of alcohol and carrying. This is a hot topic of many Texas forums, and it seems there is no slowing down of this myth - largely due to a lack of education of many instructors. "I'm a COP, and if I so much as see you with a beer in your hand, I'm ARRESTING YOU!!" - seems to be a common mantra. But it is not illegal to carry and drink alcohol.
You are indeed correct that it is illegal to be intoxicated and conceal carry, but as per PC 46.035 - only while carrying under the authority of H/411/GC. On your own property? Sure. With a rifle? No worries. Not smart, but not illegal. I'm not sure that having a firearm while intoxicated is illegal in any other situation - please, please, please correct me if I'm wrong on that one, anybody.
In the end, the rules for intoxication while carrying are the same as for intoxication while driving. Anything more stringent is your choice, and I can't fault you on that - just want sure we're not selling ourselves short. And for the sake of brevity, I understand that simple statements, at risk of being too restrictive, are better for a small brochure as this. The decision to revise is yours.
It might be good to put a link to the TABC search site for 51% locations as well.
As Grapeshot demonstrated, take anything printed by the Law Center to Prevent Gun Violence with a glass rim of salt. And a margarita...
Congrats - this thread was what motivated me to move from 'long time lurker' to 'Newbie'.
