Do you have a lot of time on your hands these days? Need a project to keep you busy? Don't feel like venturing out to a restaurant or the gym quite yet? Here is a cache to help with that. This is a 13-stage multicache along the Bluebonnet Trail in Plano. All stages, except the final container, are virtual; there are no containers to look for at the first 12 stages. You will find existing numbers at each stage that will be used to form coordinates to the next stage. This multi is designed to guide you along the length of the trail and back to where you started. Total distance is around 11 miles. It is strongly recommended that you walk or bike between stages. Fresh air is good for you, and outdoor exercise is a low-risk activity. Traveling by bike is the quickest method and would allow you to complete the cache in a couple of hours. Or go for a long walk to occupy most of the day. Or break up the stages into several days. The numbers you are looking for at each stage are either on the trail or very close by. The letters that are used to represent numbers for each stage's coordinate calculations reset at each successive stage. The terrain rating for each stage is not above 1.5.
There are 2 additional multicaches along other trails in Plano:
Quarantine Caching - Chisholm Trail
Quarantine Caching - Preston Ridge Trail
On the logs within these 3 caches is a codeword - write them down! Once you have collected all 3 codewords, you will have the password that will grant you access to a bonus cache: Quarantine Caching - Bonus.
Let's get started!

Stage 1: Posted Coordinates. Under the display case is a small silver plaque that has a phone number on it. Let those numbers be ABCDEFGHJK.
Stage 2: N 33 03.(A-G)H(C-B) W 96 4G.C(C-D)K. Small metal plaque. Beneath the phone number is a 7-digit number. Let it be ABCDEFG.
Stage 3: N 33 03.(D+E)E(A+F) W 96 4A.(G-A)E(D+F). The second line of the plaque contains six numbers. Let them be ABCDEF.
Stage 4: N 33 03.(C-A)(D-4)(B-C) W 96 4(A+A).CF(F+3). On the small metal plaque is a serial number with six digits (ignore the letter): ABCDEF.
Stage 5: N 33 03.(E+F)(C+E)(C+E+F) W 96 4(C+F).A(D+E)(D+F). On the wooden pole (either one) is a metal sign featuring yellow numbers. In order, from top to bottom, they are ABCDEFGHJKL.
**Stage 6 is missing. Use the numbers from Stage 5 to calculate coordinates for Stage 7 (formula updated)** Stage 6: N 33 03.HAE W 96 4D.(B+H)J(C+E). On the meter, below the word 'Oncor,' is a 9-digit number: ABCDEFGHJ.
Stage 7: N 33 03.HFE W 96 4J.KG(C-B). On the wooden pole is a metal sign featuring yellow numbers in two rows. Let the top row be ABCDEFG.
Stage 8: N 33 03.G(G-E)(C-A) W 96 4(D-E).EB(G-E). At the bottom of the small metal plaque is a 7-digit number. Let it be ABCDEFG.
Stage 9: N 33 03.GG(E-C) W 96 4B.BGF. The green box has a 4-digit number prominently displayed. Let it be ABCD.
Stage 10: N 33 03.AB(A+D) W 96 4(B+D).(A-D)(A+D)D. The metal object has a year on it. Let it be ABCD.
Stage 11: N 33 03.(A+D)AC W 96 4(A+D).A(C-A)(B-A). On the white sign is a 6-digit number in the lower left corner. Let it be ABCDEF.
Stage 12: N 33 03.(A+2)(C-B)(C-D) W 96 4(E-F).(D-A)(A+B)(A-F). Each corner post has a 5-digit number stamped into it which repeats every 3' or so. Let that number be ABCDE.
Stage 13: N 33 03.(D-B)E(B-C) W 96 4(A-C).EA(C-E). This is where you will find the cache.
