I am planning on doing a re-certification workshop on June 8-9 in Grand Forks, ND and after that go over to either Idaho or Washington and so another one on June 15-16. My question is how many of you in those areas would be interested and where do you think would be best. The cost of the workshop would be $395.00, and your spouse can attend free. The workshop will deal with carpet, hardsurface, wood, and expert witness. Also, time permiting we can discuss stained and polished concrete. Please give me your feed back.
