Need inexpensive outdoor storage in Portland, Oregon

How far are you willing to drive? Our indoor storage place decided to not store trailers this winter and let us know at the last minute. We had to scramble. We found storage in the $100 - $200 range but kept looking. We finally decided on the county fairgrounds that was about a half hour away. We ended up paying about $80/month for our 22 ft trailer. The only negative, you put it in and don't get it out until march.
