I have am sucker for animals in need. My home is filled with furbabies, 2 boxer rescues (one of which has 3 legs, and one that is deaf) a black lab that is afraid of himself. I have 4 rescue cats one to include a munchkin cat. I love the water! You will find me in my spare time bass fishing on Wheeler Lake, Guntersville or Smith Lake. When I’m not fishing at home, the beach is calling my name. Beach by day and fishing by night for speckled trout.
