For the last few days, the dogs have been trying to get behind things because they just know there is a critter back there. Then Page, the JR, started to lick the amp..... that black thing in the picture. So Ashley turned it over for us to look behind, etc. Well....there is a part of the amp that looks like a tunnel, maybe for heat to escape? Sound? Anyway.....this awfulstink started wafting up from this "tunnel" looking thing and made us gag. So I guess there is a critter....now a dead critter.
