Most certainly an interesting experience.
I am going to split this review into 2 sections buses and trains.
Buses.
The buses are ok from 7am -9:30 am and from 4:00pm-6:00 pm. Other than that I would avoid them like a plague. DO NOT UNDER ANY CIRCUMSTANCE ride alone at night. Do not ride the 6 unless it is that or death. There are some lines that would be great if they ran a little more often. Other than that protect whatever you are carrying and do not drop your guard.
Trains:
Trains on the other hand are great. Great price, fast travel, no traffic, and best of all no fighting cleveland weather or parking. I love taking the rapid to tower city for a movie or over to work at university circle. It is so convenient and a great price. less than gas if you think about it. At night there may be some submersive or frankly out of their mind riders but nothing like the bus. I have seen drug deals go down and prostitutes pick up johns but if you haven't seen that downtown you haven't seen cleveland.
Overall No Bus, Yay Trains. Not the best not the worst. Definitely under-utilized
