Maine - Located in the Northeastern region of the U.S., Maine was the 23rd state to be admitted into the union. Maine has four complete seasonal climates with snow in the winter, greening of grass in spring, warm summers and beautiful red and orange leaves in autumn. Self-storage facilities and mini-storage units around Presque Isle and Caribou are used to house skiing equipment, 4-wheel recreation vehicles and hunting supplies. In the summer, boats and water-sporting gear are frequently taken out of storage to sail or play in the Ocean waters of Portland, Bangor and Augusta. Thousands of storage units are located in Maine.
