I am the property owner and cachers are allowed on to the property. Please only come between reasonable waking hours (~0700 - 2200 hrs). And, please watch your step while walking on uneven spots in the yard.
You may want to pull up on the curb or park at the end of McAllister Street in the cul de sac and walk back; approximately 150 feet.
This is the first cache placed by me and my kids. They were excited to place it and it might be a bit of a tricky challenge. Good luck, have fun, and happy caching!
