Wonderful story and photos! Looks like your rifle is performing very well, as is the person behind the scope.
I just got back from two weeks on Oahu. Believe it or not, I didn't see any deer or sheep in downtown Honolulu. But I did see turtles while snorkeling and caught a small barracuda while fishing a canal with my 8 y.o. granddaughter who lives there. She caught a couple of tilapia.
The canals are saltwater, so no license necessary.
I hope you enjoyed your trip!
Congratulations on catching something besides talapia lol. Those are about all I would see down town.
