The nearest e85 gas station is 17 miles away, aka there and back would cost almost 1/4 of a tank. In this case, is e85 just completely unfeasible or what?
34 miles is not 1/4 tank unless you've contracted with GE to replace your FA20 engine with a turbofan. I routinely get around 240-260 miles per E85 tank in the city and closer to 270-290 miles on the highway at 70-80 mph. I run a Flex map from OFT using their kit. When I briefly ran an E85-only map, I actually saw slightly higher fuel economy.

But, of course, you can always fill a fuel can to help extend your range if the station is truly out of your way. Or run some intermediate mix of E85/93 to boost range while retaining most of the added performance benefit of E85. On straight 93, I will get between 340-360 miles on a tank at highway speeds (80 mph). I have no idea what my fuel economy is in the city on 93...I almost always switch to E85 when in the city.
