Suggestions before you leave:
Get his cell number,
Set a time,
Make sure you have any parts needed (including keys),
Plan to arrive at least 3 hours after your set time so you know Dennis will actually be there,
get your wife to call the shop and block all incoming calls to his line so you can get some work done,
take police tape along and surround the outside fence so no one stops by so you get work done, wear a cup, (his dogs are VERY friendly)
Boy I'm glad i got in before dennsi had his quota
