Onslow closed down a number of years back - only went there once back in 81 - & while there was talk of opening it back up, I haven't heard anything for a couple of years now so no idea what is going on there. If you are going to be in the St John area, you can go up #7 highway towards Fredericton but before you get to the Transcanada there is a turnoff for Geary & they should have signs for Speedway 660, formerly NBIS which runs on Sat nights with Pro Stock, Sportsman & Street Stock. If you are into Go-Karts, I believe there is still a track that still goes just outside Moncton & is visible from the Transcanada as you head towards NS. Not sure when they run but last I heard it was still a go there. Other than that, the only other track in NB that runs weekly are in Shediac, Mirimichi & I believe Blue Mountain up in the Bathurst area but not sure about the last 2 as I have never been to them.

Also with regards to Riverglade, they had cut back their scheduling last year or 2 & were only running something like 6 shows all year long but they had cut even them down even more so they may not even be running this year from what I was told.
