We had an exchange with our zone leaders. We met in a town up north, and I went even further north while my companion stayed in the town in which we met the zone leaders.. They stayed most of the day contacting people, and met a referral we received a week ago. He turned out to be a golden investigator. I haven't met him yet, and I probably won't meet him until next week, because we are having an exchange tomorrow with our district leader.
