Yeah from 7minutes - I see nice runda like estate - but generally the town appear shaggy for a former provincial HQ - appear informal business are all over unlike most towns in kenya.
I'd rate Meru town high though I have not been to both. Nanyuki definitely growing to be a nice town like Nakuru.
Kericho is smaller but way cleaner and organized than Nyeri. I think governor really need to work on modernizing the town - but it also good to let informal traders thrive. I have seen Karatina and was suprised by it's size.
