In order to get to Rumbara Town, people used to have to cross the blazing desert. Now, the people of Komo Dorado and Rumbara Town have dug out trenches in order to have a designated pathway between towns, and a cooler way to travel too. The trenches are about 20 feet wide and 8 feet deep, unless it is sloping up or down marking the end of the trench. Burrowing ground Pokemon sometimes pop out of the walls. Maybe it would be a good opportunity to earn some experience?
