The Illinois Tax Seminar was originally for farmers, and was adapted by all the "land-grant" schools in every state. For Alabama, this means Auburn U, and I have been going down to Birmingham three years to attend this thing. For Texas, this probably means A&M is sponsoring the seminar.
The textbook is pretty good, but doesn't have much about farming any more. If you stand to read IRS material, Pub 225 is pretty good and is strictly for farmers.
