Memorial Day weekend not only marks the unofficial start of summer, it means the beginning of the 2021 Monmouth Park racing season! Opening day at “The Shore’s Greatest Stretch” is Friday, May 28, with a first post time of 5 p.m. ET. Monmouth opened for business in 1946 in Oceanport, N.J., and since then has established itself as one of the top summertime tracks on the East Coast. Here’s what you need to know about playing the races at the Jersey Shore.
