Here is a list of dual-sport events coming up in October and November (2014) here on the East Coast (VA-PA-NJ)

October 4 & 5 - Shenandoah 500 dualsport - Harrisonburg VA   http://watr.webs.com/     I have done this in the past and is a nice 'easy' event.  I can't go this year :-(   $145 for both days

October 12 - ROAR DualSport.  http://www.rorr.org/  1 day event.  Pine Grove PA.  up near Rausch Creek off road park.   $40.   I have done this 1-day event in the past.....   good trails - a little technical.  Not sure if I am going to do this event this year.

October 25-26 - 2 day event  http://meteormc.com/dual-sport.html     http://meteormc.com/uploads/3/0/7/6/3076397/meteor_dual_sport_flyer_2014u1.pdf       NW of Atlantic City      $40 per day pre-entry, $50 per day post entry.        I have never done this event and might try it this year.  I understand it is a lot of 2-track and fire roads.  Sandy conditions.

November 1-2.  2-day event Hammer Run http://www.teamhammer.org/Dual%20Sport.htm

 45 minutes south of Atlantic City.    I have done this event in the past - good event - 80% single track tight woods riding, you might see 4 rocks, the rest of the time you are dodging trees.    $80 for both days pre-entry,  $90 post entry for both days or $50 per day.   Technical but I have seen KTM 990's on this event.  They claim they have a big bike route, but it does blend with the normal route and can get a little tough.  Lots of clutch action!  Fun event.

Let me know if any of you are interested in going and perhaps we can meet up, or if you have questions about these events and I can try to answer.....
