I guess you missed the part where 3 or 4 people said 'the laws are different in every state'.
And in Texas, the laws are different depending on WHERE you hunt also.
On a lease where you are the sole persons hunting it, most leave their stands and feeders up all year round. On some public land you're supposed to take your stands down everytime you walk out. And on some public land you may leave your stand up for 72 hours.
If you're a landowner\leasee and you have problems with trespassers and theft, your best recourse is to pursue the lawbreakers with every thing you can do LEGALLY.
Yes, it's aggravating to have things stolen--money wise, stress wise, time wise.....but the best revenge is to see that THOSE WHO BREAK THE LAW........are PUNISHED FOR IT....... and don't do it again.
