Thing is with your US events is that you'll have 6 classes or more for ROAR for example 2wdmod, 2wdstock, 4wdmod, 4wdstock, truckmod, truckstock, SC10, sportsman and more.. We only run modified in most events here and most people double up so you do get a lot of track time and in one class - 1/10th offroad modified so you do 'get into it'. There were nearly 300 entries to the Clash but only 60 drivers, we seem to prefer to race against the best all in one class here.
Also we have 2 1/10th nationals and an 8th national in June so racers are away from home a lot already in that period.
Having said all this i know that all the comments are being processed and discussed by the great minds at oOple
