As I pulled in to the driveway last night, I noticed the people 2 doors up were back from holidays and so were their dogs. I wondered where Max was; I couldn't see him in the street or front yard. One quick inspection of the back yard later, and I found him lazing near the dog kennel in the little shed yard. I took the spare panel of aviary mesh and a rake, and blocked off the gate. A couple of days in solitary won't hurt him. I then spent some time rabbit-proofing the yard -- again -- until I was satisfied he won't get out. I think I have delayed the next escape by about a week. We'll see.
