scavengermonkeys put out a series of 31 caches in the HAIL (hanging around industrial lightpoles) series for CARW2018. I didn't do ANY of them during CARW, but took a couple of stabs at the series over the spring, then finished them over the summer. Some helped me get my Planetary Pursuit souvenirs, while I finished off the series to help me earn Hidden Creature souvenirs. Everyone I've spoken to enjoyed the series no matter when they found them. So HAIL TO SCAVENGERMONKEYS for putting out these caches for us to enjoy.
A big shout out to scavengermonkeys for a job well done. If you've done the HAIL series, then you know what you're looking for. I wanted to do this sooner, but I had to order in the required materials.
