My flats skiff has been an unbelievable joy.
Allen Junek and I have been friends for about 28 years, give or take. I swear, I think he could parallel park a flats boat and not take it off plane.
As for one item, I ought to pick something like a Pre64 Model 70, but I am going to go with Bosch oscillating multi tool. I bought that thing for one hard job, and I cannot remember how many other uses I have put it to that I couldn't have done as well without it.
