Oh my goodness!! I just told my boyfriend all about this thread that I just spent the last 30 minutes reading! My thoughts and prayers are going out to you and your family and ESPECIALLY little Yoshi!! If I lived in Wichita I would be getting on my jacket to go out and search for him for as long as it took to find him!!! I'm in California though, so I'm no help
You're on the right track!!! Just let everyone in that whole state aware!! Post posters, and say reward (but I heard don't say an amount). You will find him! I know it!! Just keep positive and keep looking. We will definitely be praying for him out here.
If you want us to do anything to help your search, let me know!! I would be happy to help in any way I can! I'll light a candle for him tonight, and wish upon his safe return!!!!
