It might also be difficult for a person with poor vision to use the paths. However, the processes needed to widen and resurface the paths would have a very negative effect on the ecology of the park. The stream banks are steep and it seems to me that further terracing would increase erosion. The mechanical equipment needed to do the work leaves damage that takes years to undo.
Some people think the lights currently in the park are intrusive.
On the other hand, I believe the residents of Fisher Park want everyone to be able to enjoy the park and not be excluded because of a disability.
