Per ODWC:Isn't it illegal to transport live feral hogs?
EDIT: Argh. O4L beat me to it...
Can I release hogs?
No. Unless it is a Judas Pig. This is a population control technique in which a feral swine is caught, radio-collared and released at the trap site, then tracked down after it joins other feral swine so that those swine can be removed. The feral hog must be released onto the same private land on which it was caught within 24 hours of its capture. For more details, go online to www.ag.ok.gov/ais/feralswine.
