I think 69th is 3.2 km or 2 miles from city limits at 101 St SW. I'd love to see a 85th station because there is so much development on 85th, both existing (mostly north of Bow Trail, unfortunately), and planned. But I understand that the city studied that extension and made it a low priority compared to something like a NE extension of the blue line.
NE has had explosive growth for a long time, ideally both extensions happen but I can get why the NE one always ranked higher. Lots of significant (by suburban standards) density already built in alignment to the future LRT:
And it's not like the NE is slouching on density, such as this 600-unit development directly planned adjacent to a future Blue Line Country Hills Station extension

I agree with many points on here that Calgary's LRT and transit system expansion has hit some big real and perceived headwinds. The Greenline and BRT projects are good projects and needed, but have dragged on - Greenline with it's politically-driven delays adding years of time, the BRT with it's operations lagging the capital projects to make it perform as intended.
According to the C-Train's Wikipedia the longest gap between extensions was 1990 - 2001 (11 years) between the opening of Brentwood and the opening of Canyon Meadows stations. Currently we are looking at a 16 year gap at least, between 2014 (Tuscany) - 2030 (Greenline).
There's also seems to be very little obvious strategic planning occurring (in public at least?) that re-tests old assumptions and provides updates on key corridors (i.e. bus network redesigns, extension planning, new lines not yet imagined 20 years ago). Some of that stuff is bubbling along I am sure - but this is hardly Metrolinx or Translink that have updates seemingly weekly on all sorts of projects, plans, and infrastructure planning. Makes it seems as if not much is happening, even if this is not the case. Communications is a weakness here.
None of these issues are necessarily Transit's fault alone, as it's mostly budget and politics, but still frustrating for a city that's growing as fast as ours. The good news is the core Red-Blue network and the MAX systems are still paying dividends, increasingly so in the future as redevelopment continues to occur. Just want to see some tangible results! More busses, faster buses, more plans, more construction, more ridership etc. etc.
