20 LAB CACHES

TRADITIONAL CACHES (3 ways to find)

https://www.geocaching.com/bookmarks/view.aspx?guid=88b6e6ca-5aac-4916-864b-87ff46722beb

2. Another way to find the Event Caches after they are published is to log into your geocaching.com account and use "Find Another Player" to get to the S*W*A*G page. From there select "Geocaches Owned" and then "Traditional Caches"

3. If you wish to get notifications of the Event Caches as they are published, be sure to create a notification on your account for the Yuma area. Geocaching.com sends notifications to an email address; if you wish to receive text alerts on your phone you will need to find the email-to-text address for your carrier:
    a) Go to this site to see how to find the email address you need, MMS is recommended if available from your carrier.
    b) Once you find your email-to-text address add it to your geocaching.com account so that it can be used in notifications.
