Ok, I've asked several questions about who to rent from, getting on buses etc. DH is concerned what if it's stolen. I asked Walker Mobility and they said they have never had that issue. 80% of the time, we'll have the wheelchair with us, but for those few times we leave it parked somewhere...would it be allowed to closed it up and use a bike lock to keep it closed. The CM can still move it. The wheels won't be locked, just the ability to open the seat. How dumb of an idea is this.....slightly dumb, medium dumb or the dumbest thing you ever heard of????
