Calling MMmm!! Multi-Cache

Tribute cache or payback? He can decide!
MMmm!! has placed many Phone Booth Multis; taking us on tours around a few states in our quest for smilies. This will take you on a nice 2.5 - 3 mile hike and give you what I think of as one of those tough to find fizzy spots.

You will, of course, start where the Phones used to be and the sign can still be seen. To the left of where the phones used to be is a Transit use only sign. At the bottom of the sign there is a four digit number that will be AB.CD.

Using this number, park at N45 D(A-A).AB(A-A) W123 (A+C)(A-A),BC(C+D) and proceed up the trail to the cache at N45 (A*A)(B+C).(B+C)(B-C)(D-C) W123 (A+C)C.(B-C)C(B+C).

Checksum for parking = 48
Checksum for final = 69
