I have not done this for a while.
When I was in contact with the trolley today, it gave me a certain high!
It’s like driving on the road. There are different lanes which lead to different sights. You have to slow down when you reach the junction. You have to brake when you are about to hit an oncoming trolley. Know what’s the best part of it? I get to pick what I like if it doesn’t hurt my wallet so much.
