Here I go again

The school wants to save money this summer by not operating two buses up to school this summer like they have done for years. All the severely handicapped children will ride on one bus with a driver and an aide. What does that mean to me and my son?? My son would be one of at least 7 children riding in a wheelchair on that bus. Think how long it takes to load and unload a wheelchair from a bus. With 7 wheelchairs that will makes a long time in getting home. What if it were ever an emergency? A wreak, a fire or tornado? My child has little hope of surviving.
There are no laws that limit the number of wheelchairs on a bus in Michigan. Most school limit the number to 4 but have hook ups for 5 for that just in case situation. I am not sure what to do. I am already tired of fighting with the school.
Years ago I went into a wild rage over my son's transportation to and from school. In the summer while he attended school I discover the temperature on the school bus would quickly and easily get over 100 degrees. While arguing with the school about this situation, there was an article in the newspaper about a man being arrested for having his dog in a hot car. Dog in hot car you are arrested but severely handicapped children in hot wheelchairs that are unable to speak, nothing wrong with that. I screamed and yelled and brought it to everyone's attention. Now every bus in the county that goes to the summer program is now air conditioned. Yes it was worth all the work, but now I tired. Maybe I should just keep my son home from school for the summer. HELP ! ! !

Side note: The bus driver with the most seniority gets first bids on this summer school bus run. My father turned 75 in January and the summer drive is older than my father.
