Hit both. Start the night at LPS. It's possible their sprint feature could be done before 10. It sometimes is. Then drive down to Paragon. It's only about 30 minutes between the two. Odds are pretty good you'll make it to Paragon in time for the KISS feature. Just keep in mind, that unlike most race tracks where the ticket takers disappear by main event time, Paragon will still make you buy a ticket.
