 <h2 id="ukcaving">UK Caving Blog</h2>
 <p>
 We maintain a blog during expo on ukcaving.com . Since it is a blog, anyone on expo can post their own reports so it is more convenient for most than the facebook, twitter and instagram accounts which are each under the control on one person at a time. The 2018 blog is particularly detailed and well illustrated.
