I've just spent a few days on the coast and have had a very productive time. There seemed to be loads of great Pokemon.
Today I caught a Lapras, a porygon, a slobro, a doduo, 2X poliwhirl, a koffing, eevees, 2X magnimite, a 200CP magicarp with top stats (So happy - it's the best I've ever caught
), 2X pichachu, jigglypuffs, a growlith, lots of voltorbs, a tentacool plus some of the normal stuff.
I missed a ponyta and an electrode. 
I wasn't even pokemon'ing that much. I was on a pier, a beach and a harbour. Looking back at the list it's easily the best haul I've ever had. There was one lured pokestop but that's all.
Imagine if I'd had any incense left.
I also cashed out 8 gyms 💰💰💰💰💰
The absolute best thing though was training up my 79 year old Mum to play for me while I was driving. She was catching Pokemon like a pro. 😂
