Thanks for the info. I'll pass it on. She does plan to go at RD, but trying to push a wheelchair through the masses will take time. While the 9 year old has mobility limits and visual limits, there are a couple more kids with mental limitations she has to manage to keep hold of too.. The adults are my step son and his wife. Her mom use to go and help out but lost her fight to cancer last month, so it's just the 2 adults. There are actually only 10 kids going, which includes 2 grand kids. My stepson and his wife adopted all of their children via foster care, so they are very young grand parents (late 30s).
Just saw the update....back to the drawing board.
