Sorry to revive this old thread, but I can help. I have lived in and brewed in Tyler for more than ten years. As of November 2012, Tyler is finally "wet," i.e., we can buy beer and wine at a grocery store or convenience store/gas station. So he may be able to get a grocery store like "Fresh" to order kegs. Assuming he cannot, he needs to get in touch with one of the county line liquor stores (still no liquor sales here) like "Fat Dog" in Coffee City or Tuckers in Winona. Tuckers will deliver for about $6. Either should be able to special order any number of good craft beer kegs. Give them some notice because I'm pretty sure (from past experience) that neither of those stores is going to have much in stock.
