Wii Sports Resort - Island Flyover help?

I'm trying to get the "Balloonatic" stamp in WSR and I'm missing 4 white balloons. The only problem is I've searched everywhere I can think of. I've spent at least 6 hours total looking all over the place and frankly I'm really tired of wasting my time like this. I can say for sure that there are no more off the central island, ive gotten the ones on all the boats, the extreme canoeist, wedge island,etc., and the town, caves, lighthouse, volcano, ruins, beaches, high up places with all the trees, roads, and the entire area between the volcano and the town has been searched completely. does anyone know of any obscure locations the last balloons could be? Please help!

Oh wow, I'm having so much fun with this mode in Wii Sports Resort at the moment. I've got just over 60 of the markers so far.

One obscure white marker I can think of is the plane formation that you see over the ocean sometimes - best to try to find this at night when the planes are lit up, because it moves around in the sky instead of staying in one specific location, and so can be tricky to spot.

Otherwise, your best bet is Google, my friend.

Yeah, I've already gotten that lol.

Thx for the support tho.

Nvrmind, I finished it. Like I predicted, they were in an obscure place between i points on the beach.
