Rei7 i always conquer some gym before i go to work to collect coins.

soket yes, bukit teratai near taman muda.

today i was able to conquer 4 gyms and collect 40 coins. thanks to team instinct because they help me to fight off our OP teammates and they put their low cp pkm to defend, so i was able to use just 1 of my atking pkm to conquer them.

There was 1 gym in teratai that was level 7, i can't even go there to level up becoz the pkm defending the gym is too powerful. but this morning i saw it is gone and took over by team instinct, took the chance to take over.

Some of my personal experience 

1. Dataran Merdeka
4. Sultan Abdul Aziz Shah Golf & Country Club
6. Went to Penang last week, full of Voltorb in Georgetown
8. Caught mine at Desa Park City
9. Caught mine at SS15
11/12/13. Region exclusive, some said can get from egg
14. Caught mine in Georgetown too
18. The river spot between Dataran Merdeka & Masjid Jamek (can hunt for Charmander at the same time)

thanks for the input. will try my luck around.
I filled up quite a good chunk of my pokedex thanks to my 3days PD trip. haha
