Or just fish with someone who is or gets part of their income/retirement from it
Unless it has changed since I fished the TOBI and the LOBI, both members of the team must get something like at least 80% of their yearly earnings from the oilfield. I have no doubt that there are probably some who do not adhere to this as it is unlikely they will get caught. However, again, unless it has changed in the last 8 yrs. or so, both must be in the oilfield. Not all oilfield tourneys are like that, but these 2 at least were at one point. The Red River Oilmen's Challenge is one that only 1 member has to be in the oilfield and I am sure there are others.
