Wow True_shot I really feel bad for ya man.There may be only a few guys on here as well that i may lend my equipment to and these guys know who they are.
I know this kbacon guy from the forums only,not on a personal bases,but maybe wouldent jump the gun right away.Is there any way you can call the postal company and ask if there is a package there for you.
Like others have said,go for a drive,make your presence and get your bow back at his front door,I'll tell ya i would not hesitate in the least.
I really dont want to make matters worse,but you said you cant contact him through e-mail,and his phone was disconnected.He is still living at the same addy I hope or now we have some problems.
Like NUBO said,Hopefully its something like a money issue,or just having a real bad go at life right now,we have all been there one time or another.Hopefully this guy loggs on and sets things straight.
Good luck and keep us posted
