Today I prepared for our trip to Puebla, starting tomorrow. I had bought some small plastic storage boxes which closed very good thanks to clips to the sides. I had made several small holes in the lid to allow for fresh air in, and moisture out. I also turned the UV LED scorpion detector I made some time ago into a portable version. It was very unlikely that Esme and I would go out in the night to hunt for scorpions in the field, but yet I decided to take the UV light source with me, one never knows what one can find in a hotel room...
