Being a newcomer to this area, I have thought about making a cache as a means to say hello to fellow cachers around. An easy hide in a small green area called Maryvale Park should not take too much of your time. If you go with kids, you can stay at the playground, try out a basketball field, or even grill something for dinner. The spot itself is reachable with a terrain stroller, but would be rather challenging for a wheelchair.
If you are at the right place, you should be a bit covered from muggles, yet still pay attention. Please be gentle 
BYOP!
