maximizing bells for both you and your neighbor

I can confirm that once you run out of friend points, tapping on the cannon or tunnel just nets you cash, my strategy is going to be a modified cannon hunting- go through my 75ish neighbors tap on cannon/tunnel if I see it otherwise just tap on one building ( and then see how many friend points I have left and finish the daily total at the same time) because I like a time ordered visiting list...I tried the constantly revisiting because it was needed during Valentine's day and found I'm much more likely to be a consistent visitor if I set one fixed time and visit versus hunting over and over again
