Hi. 🙂
@AARPJanelleM -- What @TimothyS417378 has revealed (for the webmaster's attention to correct), is that when you go to: https://www.aarp.org/, and scroll down to the bottom of the page (see here as an example):

Selecting the state of 'West Virginia,' and clicking on 'Visit State Page,' you receive this:

It seems to be a broken link. I thought 'region' being in the url was the problem, because when you remove it from the url, the WV state page comes up, and no 404. You can still get to the state with this link, too: https://states.aarp.org/, but the State of West Virginia provides no error here.
It's just a 'heads-up' for the webmaster to fix the 'West Virginia' link from this page: https://www.aarp.org/, located at the bottom of the page. This fix for the 404 is with removing 'region' from the url.
Thanks, @TimothyS417378 for bringing to the forefront.
