Sometimes we let things slip, and this is one where we did!
The Terrain Rating of 1 was originally reserved as the indicator that a cache is handicap-accessible.
There was a lot of controversy over just what was a handicap, and not having a good answer for that a number of us Reviewers stopped enforcing the guideline.
We have agreed to use a still-fuzzy but more commonly understood and easier-to-evaluate standard of 'wheelchair-accessible'.
Yes there are degrees of capability even in that - I can take a wheelchair places lots of folks can't walk, for instance, and go on crutches to places most folks think an old fat one-legged fella can't get, and I am sure that you know quite capable yet disabled folk like that that make handicap ratings difficult, but let's agree please to use a simple understanding; one should be able to roll up to, find and reach the cache without standing.
No curbs, ditches, soft sand or other impediments between the parking area and the cache itself.
Since this hasn't been adequately defined or enforced most of us don't think of this when we are listing a new geocache.
Many of you will have noticed that when you listed a new cache in the last month or so with a Terrain Rating of 1 you got a note from me asking if the cache is wheelchair-accessible and asking you to raise the Terrain Rating to 1.5 or higher if not.
I have been sending the note and trusting that geocachers would make the change to the listing on their own, rather than holding up the listing while the owner makes the change.
The response, unfortunately, has been underwhelming. Therefore, I will have to hold all 1-terrain-rated new listings until I hear back regarding my note unless you tell me in the description or a Reviewer Note that the cache is indeed wheelchair-accessible.
I am asking you to please help me with this.
Since I am far from infallable, often review caches at 1 a.m. after a long day, and otherwise may overlook this detail, I need you to keep the issue in mind and use 1.5 or higher by default when listing any cache not wheel-chair accessible.
