Czech and Tenkara -- Flyfishing?
I have nothing against Czech and Tenkara fishing methods. They work and will continue to grow in popularity.
I do have a problem calling them fly fishing.
Throughout my life I have fished with a cork for panfish. I really like sitting and waiting for the cork to bob. It's one of the most relaxing blood-pressure-lowering activities around. That's probably why I like watching the popper disappear on a popper-dropper rig.
But...I cast the popper dropper. I use a cane or jig pole for most of the cork fishing -- no casting.
Tenkara doesn't seem to present itself as fly fishing, just a method that catches a lot of fish with specialized equipment.
Czech fishing claims to be fly fishing.
