Getting back to the dulcimer

Finally retired... and after being a church organist/keyboardist for 30 years it is time for some fun (not that doing what I did was not fun.. it was not work at all... sometimes I wondered why I was paid... I would have done it for nothing but I didn't tell them that).

I have had the dulcimer for 2 years and rarely touched it. I am looking for a good DVD/Book lessons. We are going to camp host for the Oregon State Parks and sometimes the internet will be limited. I looked intoStephen Seifert DVD course but can find no reviews on him. Being a piano major in college, there is not an issue reading music...

Can someonesuggest a good course to learn? I work and learn better if I am on track.. sometimes I can get distracted... if you know what I mean....
