Perhaps not as rare as one might assume.
I definitely remember Shirley MW0YLS (RIP) waiting on 999 until an activation of her local summit Hope Mountain GW/NW-062 for the MG. Colin @M1BUU set his MG activation up for his favourite Whernside G/NP-004. I’m certain there are loads of similar examples.
Not me though (Cadair Berywn GW/NW-012) or Jimmy @M0HGY (Corndon Hill GW/MW-013).
It would be interesting to see a list of activators’ first (mine was Shining Tor G/SP-004) and MG activations - but maybe on another thread so as not to hijack Ben’s event!
