Started fishing with these guys a couple years back. It's a great time and the only real option for an individual trail in the Fall. It continues into Spring when we all get busier, but you only have to fish 4-5 to qualify for championship at beginning of Summer. You can accomplish that this Fall and then fish the spring tournaments that you can make it out to.
Yes there is a co-angler chance, but in 10-15 tournaments I have pulled one co-angler, it was the director who had boat issues and we ended up having a blast that day and both weighed in solid bags. I feel this part keeps people away, but not only is it not a big deal but it seldom even happens. Unless your name is Rick and then you can about guarantee to draw a co-angler! Most co-anglers I have seen at one event is 3 total and there were over 20 boaters there.
Seriously though, in most trails above the local weekend warrior level a co-angler or at least someone in the boat is part of the equation. Might as well get used to it.
We all love to fish and the fall is a great time to do it. Give ABA a chance and see what you think. I did and have only missed one tournament since then.
