Eliminating landfills. Turning waste into a resource. Challenging outdated paradigms.

Checking the R3enc twitter followers, there's a follower named James Walter, on James Walter's twitter account, you'll see mention of his blog: http://waltersandblog.com, checking whois.net again, that domain name is also registered on bluehost.com. Bluehost.com isn't a wellknown webhost, so it's definitely not a coincidence that those two sites are related. Anyways, just in case you don't have the information:

Also, there are some public records with New Hanover County Register of Deeds, where Robin Grathwol has business relations with Grathwol Property Holdings LLC:
GRATHWOL PROPERTY HOLDINGS LLC 2905 MARKET ST (910)-256-3021
That company may have been owned by Ann Grathwol, which, from what I gather from a Power of Attorney, is Robin's mother. ( Robin D. Grathwol and Ann F. Grathwol ). It looks as though Ann Grathwol passed away in July of 2009.

Anyways, I was bored. Time to get back to Dragon Age 2.
