Until the end of January, a massive pony collection is currently on display at a the Cascade Park Community Library in Vancouver. The collection includes ponies from older generations along with G4 and beyond. Apparently there are 344 in total, and it's not even the complete collection.
You can find the article abbout it reported on the Columbian over here. Library hours are 8AM-8PM Monday through Thursday, and 9AM to 6PM on Friday and Saturday.
Thanks to Rarity mlp for the heads up.
