CLASS INFORMATION
CLASSES
Racing classes are determined by the amount of modifications to a machine. MWRA and it’s officials reserve the right to order an inspection of a vehicles modifictaions at any time or if a top three race finish is protested. Anyone found in violation of the class rules and limitations will be banned from the series for the remainder of the current season. The placement of the race in question will be forfieted to the next runner up. It is MWRA’s perogitive to hold a fair and honest competition and we retain all rights to maintain this.
GROUPS “A” and “B”
The MWRA series races in two groups within each class. GROUP B is for models 700cc displacement and under. Group A is for models with 701cc or over. Scoring will be recorded for both groups within each class. If a group has more than fifteen entries at a particular race, MWRA may offer a group/class exclusive heat.
GROUP “A” HANDICAPS
Due to the recent increase of performance UTV displacement, MWRA reserves the right to apply an elapsed time handicap on some models in Group A to insure the most even competition. All handicaps must be agreed upon with a vote by all active MWRA officials. In the event of a handicap enactment a racer may chose to advance to the next class.
RUN GROUPS
If a particular racing class has less than five entrees at a given race the entrants heats will be combined with the heats of the nearest class with less entrees. Likewise, if a group has greater than twelve entrees the group may request their own Run Group and run their own heats. MWRA officials reserve the right to refuse Run Groups if the track, weather or timing become a factor.
STARTING POSITION DETERMINATION
A driver may not qualify more than one entry per class. The starting position of each heat will be determined by a random drawing. If an entrant is not present for the drawing they will automatically be placed at the end of the field.

We are looking at doing a 4 or 5 race series for the first year.  I'd like to get as many people down here as I can in the spring and get their opinion for the track.  I'd like as many peoples input on how to change the track for side X sides.  We will have to keep alot of it for our MX series but we can reroute the whole track for side X sides. Everyone that wants on a contact list e-mail me at acad54@aol.com and just say "put me on the racing list"

Third Rad?  Maybe its time to look at relocating to the rear.

Is your icon picture from the dunefest trip? Great shot.
Sorry I missed you there.
I saw ravencr a few times.

Yep, it's one of the many awsome pictures Chris took.  Maybe we will meet in Moab sometime.  If they ever quit having the rally during school graduation!


How many kids you got?? You have to run out sometime lol

Meagan graduates in May 2010.  And I'll be in school for 2 more years.  So unless the dates change I won't be at the rally until 2011.

WOW! That looks like something that I would do!  tongue  How fast were you going when you hit? Any damage to the rhino?

I was goin about 50 when he stopped in front of me.  I slid about 60' before I hit him.  It bent the steel bed on the Rhino.

I hear ya...my only rule when I drive someone else's rig is I fix it if I break it, and vice versa. smile

Chris

RULES, RULES.... You and your RULES.....  tongue

I'm pretty tough on stuff myself, so I'm not worried, but it will be in good condition in Moab, because I haven't driven it for months! smile

Chris

That's cause ya break it everytime ya drive it. lol I guess I don't have alot of room to talk though.

That sucks, There is $1500 plus in damage sad

Oh, don't I know!!  LOL
This will be my third radiator.  I keep meaning to have someone build a bumper that will protect it.

We're gonna take before and after pics, because knowing these boys in UT and they're typical refusal for tow straps, we should have some good after shots! smile

Chris

That sounds remotely familiar.....
