You'll need a cross bike with low gears, at the very least, to make it up this. Here's my report from my first successful attempt after getting my new cross bike: "The dirt road is very, very messy the whole way up, with a nasty combination of large gravel and soft dirt. Conditions today were just about ideal, since it rained the last couple days but was pretty cold last night. As a result, the track wasn’t super squishy. The gradient for the first section is upwards of 20%, and definitely the hardest section of the whole hill. First two attempts ended in failure. Then I got the brilliant idea of climbing seated and in the drops. That kept the front wheel mostly on the ground and the back wheel from skidding out. The third time I just cleared the steep section when I lost my balance and had to put a foot down. Rather than try again, got myself going and made it through a section where the grade eases (to around 10% probably) and then it kicks up again. I would have made it through the next section, but I hit a rut and lost my balance again. After that section, it flattens out for about 100 meters, before kicking up very steeply one last time to the Tower. I made it though that without incident, though it was tough."

Hardest climb in Rhode Island? Very possibly.
