Americans with Disabilities Act of 1990
Make sure that all people with disabilities have equal access to everything that people without disabilities do.  They have to create reasonable accommodations if this would help make things equal.  (For example, see the picture above: a state park has built a wheelchair ramp so that people in wheelchairs can fish in the same park as people without disabilities.  Without this ramp, people with disabilities would not have equal access to the park, because they would not be able to fish in the park like people without disabilities could.)
