Our LGC meetings are currently in an inaccessible place- not much in it, there is a ramp at the front of the building but there is a step from the pavement onto the site.
I did eventually get the point across but it took a while- now waiting for them to get a portable ramp so I can see if the rest of the building is accessible.
I refused the assistance offer as the building should be accessible without assistance.
Over the past few years I have learned to be pretty bolshy about access and independence but it is essential that those of us who do have the self confidence to make a fuss on our own behalf, also take a pan-disability view and ensure that the venues are properly accessible for everyone. That may involve becoming the disability officer and pushing your branch or CLP to send you on an access auditing course.
