Not bcdata so changed title. Need regional district kmzs to add to background layers or better yet bcfishpass https://github.com/smnorris/bcfishpass/issues/113

Just FYI, there is another road dataset that should be available in the next few weeks - the Cariboo region is building and maintaining its own cleaned resource road layer.

I'll evaluate it once I have it in hand for this project https://github.com/smnorris/roadintegrator/issues/31 and modify bcfishpass to use this source rather than DRA/FTEN for the region if appropriate (for resource roads only, they defer to DRA for 'demographic' roads.
