Becky Leach


It took Becky until recently to learn that I truly love the water.  My first real rafting experience was in 2019, and it is now her favorite thing to do!  She has introduced her family to whitewater, and they think she’s a little nuts.  They paddleboard together, float the Boise River, and just bought a kayak.  She loves to perform; singing in the choir and on stage in Broadway musicals!  Becky lives in Nampa with her family, on a hobby farm where they raise dairy goats, llamas, and chickens.
