We pray
with the Saints. They're just far better at prayer than we are (since they see Christ face-to-face), so we ask for their help. In this sense, you could say that we are praying
to but only in the sense that we are asking them to pray for us, just as you would ask someone else to pray for you.

First a definition: "To pray," as a verb, has two very distinct meanings:
1 : to make a request in a humble manner
2 : to address God or a God with adoration, confession, supplication, or thanksgiving
It is only in this first sense that Catholics "pray" to saints. "To pray" is simply to ask, and it is a common English word as these examples will show: "Comes now Petitioner and, having filed his Motion in Limine, prays this Honorable Court to grant..." or "I pray thee, sir, might I borrow your book?". In the first instance, the Petitioner is not worshipping the Court. In the second, the potential book-borrower is not worshipping the book owner. And if I ever ask you, "Where have you been, pray tell?" I am not worshipping you, trust me!
All worship in the sense of latria is God's alone. All grace comes from God alone. Only Christ can save us. Please read these three sentences again; they are core Catholic doctrine as taught for 2,000 years.
OK, so why pray to saints? We pray to saints to ask them to pray for us, in the same way you might pray for me if I ask and I would pray for you if you ask. Christians are called to pray for each other: James 5:16 "Pray one for another... The effectual fervent prayer of a righteous man availeth much."
I emboldened parts above so as not to get confused between prayer to/with saints and Prayer to Christ.
