i really like birds. they're pretty neat. >> "lockup" crews have met hundreds of inmates facing long-term sentences. for some like dale veers at iowa state penitentiary, that means the chance to pick up a new skill or two. >> you start out with a block. then cut it down. and then i keep grinding and shaping it until i get it where it's supposed to be. >> a life sentence for kidnapping has given viers a chance to master bird carving. >> i kept the very first bird i ever carved because i just knew that i would get better. that is the first one i carved. that's my duck head. duck's getting a little bit better. i have another bird here.
