For the past 20 years my now (84 year old) Dad has used a wooden ramp to put a slope between the pavement and road outside his house. He refuses to pay the money for a dropped curb.HE religiously pulls out the wooden ramp and uses it to get out the drive, then put it away, and uses it again on his return. My in laws put small concrete ramps in line with their car tyres ( about 8" wide). Aren't people funny!!
