For his response, that got me pointed in the right direction.

First, we need to add the JS to our head tag.

<script src='https://www.google.com/recaptcha/api.js'></script>

Next, we add our form.

<form class="form-3 pics Setwidth" name="ContactForm" action="3.asp" method="post" onsubmit="xmlhttpPost('3.asp', 'ContactForm', 'Contactdiv', '<img src=\'graph/pleasewait.gif\'>'); return false;">
<label>Name</label>
<input type="text" name="name" />
<div class="g-recaptcha" data-sitekey="YOUR-SITEKEY-GOES-HERE"></div>
<input type="Submit" name="Submit" value="Send Message"  style="width:150px;"/></div>
</form><div id="Contactdiv></div>

You will need to the new reCaptcha 2.0 Site Key for this.
Go here: https://www.google.com/recaptcha/admin
Add a new Site Key for your website.
For local testing, you will have to test with
127.0.0.1/site.asp
It will not work with a static IP Address, or with localhost anymore.

Next, we add in our code for the processing page.
3.asp

<%
strname = request.Form("name")
captcha = request.Form("g-recaptcha-response")
if strname = "" then
response.Write "Please provide your name"
'next, we are going to challange the reCaptcha, to make sure that it is not blank, 
'and there is NO way around this. If it is not blank, then we send them a message.
elseif captcha="" then
 response.Write "You have not completed the <strong>reCAPTCHA</strong><br />Please click on the blank box, <br />and fill in the sequence of characters.<br />Thanks You"
else ' If the user has completed the reCaptcha, then we send a message letting them know.
response.Write "Thank you for trying out the <br /><strong>ASP Classic / Jquery reCAPTCHA 2.0</strong> demo."
end if
