hunt in a subdivision with lots 10 acres or less in an unincorporated area of a county if the commissioners court, by order, prohibits the discharge of a firearm or the use of archery equipment in such subdivisions. (Contact local county clerk and ask about 235.022, Local Government Code.)

regardless of the size restriction I would suggest checking with local authorities to insure you are legal.

anything between Conroe and Cleveland you could invite me out.
