I am planning to set a series of wheelchair accessible caches along a dissused railway line which is now a footpath/cycleway. I would like to place 5 caches along a 1.5 mile stretch which offers great access and an interesting rural location. I appreciate that they will be relatively close together but as there are not may wheelchair accesssible caches in the UK I thought that it would give a great opportunity for those with limited acces to knock off a few in a single trip.

1) Is this a good/acceptable idea?
2) Is it ok to mix real and virtual caches in the series to provide variety?
3) Is it ok to add them over a 3 or 4 week period or must I get them all ready before sending them for review?

Sorry there are a few questions but thes will be my first caches and I'd like to get it right.
