I remembered that there was a wheelchair thread last summer so dug it out to reread. My neurotransmitter test was a bust, even after continuing it an extra week, so now we are discussing how to get me from the shuttle, through security, and to the waiting area for a plane trip. We will buy a wheel chair before we set off on our three week trip to Yellowstone in June, but I am against trying to wrangle one ourselves through LAX and then Detroit for my cousin's wedding in April. Reading the stories about waiting and waiting for an airport wheelchair makes me not want to go down that route. We might look at the walkers with seats. I can walk for short distances, walking much further even using a cane is painful. I can fairly comfortably push a cart in the grocery store, which makes me think a rolling walker could work to get me to the gate. Then Cliff can deal with our two rollaboards and his small backpack.
