1. Go to bitaddress.org and save the page to hard drive.
2. Take computer offline and generate keypairs.
3. Send coins to generated address(es) and print out private keys.
4. Etch keys onto metal (I used a Dremel though other methods may be better). Two copies stored in separate places might be wise.
5. Burn paper copy of keys.
6. Wait 10 years, buy Aruba.
