This is the 18th in a series of hides along Preston Ridge Trail, this segment being in Plano. Some of these hides will be park 'n grabs, others will require a bit of walking. You will see a large variety in the types of hides and containers used. This trail spans several miles, so once my series is complete you will get quite a good workout finding them all!
You are looking for a magnetic container. Use the hint if you need it.
