On 21st November 2010 Team Steve Cat released an 800 cache series along a 90 mile stretch of Route 66 in California, America. So if you are planning your holidays and want to get your numbers up then this could be the series for you. All the caches are set on the same side of the road so the series can be done East to West. GC2J17A is the first in the series. Is this the largest Power Trail?
