Actually, thankfully, my only concern with the firearm method is the sanity and hearing of the neighbors and of course safety in making sure there is no mistaken path of a bullet as I live in the county and don't have to worry about the city regulations of shooting a firearm within city limits. Out in the county I just have to worry about waking or scaring the neighbors but given it's a fairly condensed neighborhood and one that I do have to concern myself with potential ricochets I either will choose my shooting position/platform very wisely or just rely upon the live trap as I do have a secondary location in which to release the creature.
As for the directions or suggestion of what to do if a wayward skunk gets into the trap my luck and fortunes would surely dictate a smelly end to the endevour and one that I would not find too amusing. I've seen some videos of skunks that have got their heads stuck in bottles and containers and watched them as they were freed from their situation and in most cases they weren't to polite to the ones that freed them but rather was intent on leaving something for the person to remember them by. Maybe I won't have to concern myself with a skunk and I do believe most are right about the armadillo so we'll see how lucky I am at capturing it next week. I'll update with photos if things work out.
