Amtrak is offering a fantastic flash sale this Mother's Day weekend that is going to make you want to travel by train for your summer vacation.

I have always wanted to take a long train trip, but let's be honest, it's usually cheaper to fly.

But this weekend Amtrak has a flash sale event happening that let's you buy now and travel anytime between June 1 and September 30.

They're calling it their Unconditional Love Flash Sale and are using Mother's Day weekend as their angle, encouraging travelers to visit mom via train.

Whatever your reason to travel however, the sale is a good one.

All weekend long you can buy one adult ticket aboard any Amtrak train across the country and get one free.

Yes, BOGO Amtrak tickets this weekend only.

Places you can travel?

How about a pair of one-way tickets from Boston to Portland, ME? Just $29 with the flash sale.

Boston to NYC one-way is $83 for two tickets, $125 aboard an Acela.

NYC to Washington, D.C. one-way is $96, $173 on Acela.

You could check out the Pacific Coast via train by traveling one-way from Los Angeles to Portland, Oregon for $121 for two. What a view that would be!

The summer adventure possibilities are endless and the tickets are BOGO all weekend long.
