where to get bones

i see a ton of dead dogs n deer, I could get the ribs out, but getting a shower afterwards'd be a mite of a problem, as well as artificially bleaching the bones. also, i try not to carry a large enough knife to be useful in that situation. I could find one thats decomposed enough to just pick the ribs up though
 
Honestly you will find alot of bones along train tracks that you could imagine animals living near. if the tracks go through a secluded area or a forest, you can bet that you will find alot of animal bones. I used to walk my trolly tracks when I was younger and get trashbags full of animal bones. Just be safe and dont get a ticket like i did. lol dumbass
