can a person on crutches get on a ride

Yes

Yes. There are some rides that persons with crutches or on a wheelchairs can go

Yes, some rides are a little jerky. So I would be careful depending on the persons condition.

I saw people with crutches in the park in passing but didnt see them ride. I figure if u can handle getting jerked around in the ride and our able to actually get in the seat you'd be good to go.

Yes, as long as there is room to store them on the ride, or you could ask one of the workers to hang on to them for you.

Im not sure. I would call the park and ask, but honestly I wouldnt think it should be a problem.
