I don’t think I’ve seen a collector at our shul minyan in at least 3 years.
Collectors seem to prefer cities where they can hit multiple places in a day.
Takes too long to reach the hinterlands to collect from a small minyan.
Once a quarter, our pushke committee takes the funds and distributes them to reply to the assorted request letters received as well as the regulars.
Twenty years ago when I was still living in a Connecticut city with about 6 orthodox morning Minyanim visiting collectors were on the wane, maybe one every 8-10 weeks.
Stayed overnight in Brooklyn this week (Shevah Brochos for my daughter) and was besieged by collectors at both minyan and trying to ‘crash’ the Shevah Brochos at a hall. I had prepared for minyan and had 25 singles in my pants pocket (after what the chasunah cost me, big deal). The hosts of the Shevah Brochos arranged to have personnel at the entry to the hall who admitted only those on the invitations list. No ‘crashers’ of any type entered. The collectors were each sent away with a $5 bill.
