Don, here's a few more little tidbits from someone who has prosthetic lenses and a few prosthetic teeth:

1. Handicapped parking places are, strictly speaking, only such IF there is a sign posted on a pole (where it's visible in snow or if the paint job on the lot wears off).

2. Automatically opening doors are NOT ADA-required, even though they should be (mothers with strollers appreciate them too).

3. If you have a plan to make a place which isn't ADA-accessible come into compliance, that's all that's needed. No need to do more, just make sure the plan's available if you get inspected.
