Major Interstate routes are designated by one- or two-digit numbers. Routes with odd numbers run north and south, while even numbered run east and west. For north-south routes, the lowest numbers begin in the west, while the lowest numbered east-west routes are in the south. By this method, I-5 runs north-south along the west coast, while I-10 lies east-west along the southern border. The east/west interstates are 10, 20, 30, 40, 70, 80, and 90. The north/south interstates are 5, 15, 25, 35, 45, 55, 65, 75, 85, and 95. To qualify for this cache you must have found a total of 17 caches in states where one of the major interstates listed above passes though.
For example to claim a find along Interstate 5, you must have found a cache in either Washington, Oregon or California. For Interstate 10, you must have found a cache in either Florida, Mississippi, Louisiana, Texas, New Mexico, Arizona or California. You cannot use one state for two different highways - so you could not use California for both North/South and East/West. However, because I45 is only in Texas and I30 is only in Texas and Arkansas, you can use Texas twice for both N/S and E/W. That will be the only duplicate state allowed. Only Interstate Highways that end in either 0 or 5 will be used.
The D/T rating on this cache is based on the time, distance and effort needed to find the caches to qualify for the challenge. The cache is not accessible from I40/I85.
To get credit for this cache, please include in your log the cache, state and interstate, post a screenshot or attach a bookmark list.
Here's an example of how you would qualify for this cache. Caches do not have to be on the interstate, just in a state each interstate runs through.
5 - California - GCXXXX
15 - Montana - GCXXXXX
25 - Wyoming - GCXXXXX
35 - Iowa - GCXXXXX
45 - Texas - GCXXXXX
55 - Illinois - GCXXXXX
65 - Kentucky - GCXXXXX
75 - Ohio - GCXXXXX
85 - North Carolina - GCXXXXX
95 - Rhode Island - GCXXXXX
10 - Florida - GCXXXXX
20 - South Carolina - GCXXXXX
30 - Arkansas - GCXXXXX
40 - Arizona - GCXXXXX
70 - Kansas - GCXXXXX
80 - Nevada - GCXXXXX
90 - Massacusetts - GCXXXXX
Congrats to ItsSkeeter for the FTF!!
