Frustrating Friday!

Spotted this great crawl and body pit in zone 4 this morning and was really excited as this was my first pit too prone. I probed the whole area and couldn’t find the nest. Thought it must be my inexperience, so James probed it but didn’t find anything so Emily tried with the same result. Last chance

went to Buddy. Same results, frustrating because of the amount of sand she piled up. So two NNC today, this one in zone 4 and one in zone 5.
