Maybe someone can chime in with a better answer but mine stays the same as I posted before. I really wouldn't know how to find specific areas on the lake without GPS. You can probably get free GPS on any smart phone. Coordinates for lake locations are easy to find online. If I didn't have GPS I don't know that I'd personally even be able to find A can regularly... I know where it is but on a slightly choppy day or a day with tons of boats out those markers can be really hard to see. Especially the reef markers... Adding: Not to mention that you can feel like you're in the same place out there and be a mile or more off...
