hi there! i went to eureka damn last weekend for the first time and it was ausome! NO its not just mud, thats just what the pics look like. there are tons of places for sport rides. In fact last weekend i was 1 of about 20 riders there and about 12 of them had sport quads. theres are some really cool trails, hill climbs and muddin action there. If you want easier directions go to mapquest and make the start locactioonion ur location and the end location Ft. mccoy. go through ft mccoy over the big bridge. atsek 1st left then take a left 1/2 mile down the road. it is really a cool place. Im going this saturday if you are interested and there bound to be more peoplr there cause they said they go there every wkend hope u can make it!
