Paco,
Rick's lessons are $250 per day. I drove to Arkansas from Wisconsin, studied under Rick for three days, and stayed in the MicroTel in Conway. When I added up all the expenses, it totaled just under $1,200, including fuel for my truck, and food.
When I added up how much I have spent on archery equipment in general (some of which did not help me at all), the $1200 seemed very small by comparison.
For me,it just made good sense to get some lessons. To put it another way,I am an electrician by trade, and I don't think I would have ever gotten to the "Master" status required to open my own shop, had I not started with my Apprenticeship.
I'm not a great trad shot yet, but I feel I have the basics to get there someday. I can still hear Rick's gentle voice over my shoulder, guiding me. It was a great experience. I enjoyed making a new friend as well, and so will you.
