I know you are busy, the entity of ownership is drinkard/parr LLC. The only way to avoid estate taxes is a living trust and after the rockefekkers et al got theirs the government changed the rules so you cant escape them.
Estate taxes
[link|http://en.wikipedia.org/wiki/Estate_tax_%28United_States%29#Deductions.2C_the_taxable_estate.2C_and_the_tentative_tax|http://en.wikipedia....the_tentative_tax]
For taxable estates below the next threshold value of $1,250,000 the tax is $345,800 plus 39% of the excess over $1,000,000.
since it appears that the land is most of there assests, they have to cough up 400k to keep the dirt. I dont know if there are other assets. To me that is excessive taxation on the heirs. No one living has to cough up 35% or more of their taxable income but dead people dont vote.
thanx,
