Riiiight. Ride hundreds and hundreds of miles in MTB shoes and pedals for the off chance that you will have a bridge go out the night before and you have to cross 30' of ravine then not know how to clean your cleats before you get back on the bike.

Yeah. That's real smart

That's like the guy mountain biking for years with road pedals for that 30' paved section as he crosses a street.

Evaluate the job. Pick the right tool.
