Some thoughts from last weekend I hope you'll find interesting:
Mansfield Speedway - I only got 2 slow laps before it started raining (weather said 2ish, not 12:30!). IMO, the track has a rhythm lane that could be tempered down/tabled, and they will need time to figure out their soil, watering, etc. They did offer a rain-out ride anytime this year, which is very considerate, as it was spendy to get in ($20 track entrance and $30 practice). I'll go back after they have a few events.
Honda Hills - In certain sections, they added some materials to the soil. In others, last year's rocks had baby rocks over the winter. I know it will always be an issue there because of the line of shale that runs through that area. They made a few track changes, like a new double off the ski jump, and they somewhat fixed the big double in the back by making it into 2 smaller triples. The conditions got away from them, and dust became an issue 2ish. I do believe they are trying. Additionally, Sat was part of a race weekend, so they asked if you were there for the weekend or just to practice. Large turnout. $40 practice cost.
Briarcliff - So nice to be riding on that soil! With a few exceptions, the track layout is pretty much the same as late last year, just running in reverse. Things were soft and early in the year, so I basically just rode around, lol.
