I often take an instrument with me when I go to various places. Because I play several instruments which the average person has not seen or heard, people often stop, listen, and ask questions, and thank me for playing & talking to them. [is that a harpsichord? it's an autoharp. is that a sitar? this is a mountain dulcimer.] You don't have to be a retired music teacher to do this, either! Crazy Little Woman & Leadfingers have set a good example for us. Most of we 'Catters could take the Gospel of the Mudcat to the masses, whether it's tooting our Flute while camping, sitting at the beach with a Uke, or taking a Guitar to the park for some pickin' & grinnin'.
