Smakzone, Jaegers, Oklahoma DDay, Battle Creek, The Front, Paint Games Plus North, Excelsior Springs Paintball.
Of the feilds listed only Smakzone and Battle Creek can compare to Bailey's for scenario play. The Front has potential but runs mostly one day scenarios.
Bill Bailey has, IMHO, one of the top scenario fields in the state of Missouri. The field has a wide variety of terrain and caters to the scenario player.
Wide tank trails allow for same play againts PAV's as well as allowing for an easy walk back to the deadbox. The terrain runs from flat to mountainous and has a good variety of plants from bamboo thickets to pine forest.
The Battlefield hosts several scenarios a year and I have been fortunate enough to play three there. During paid play, there are adequate referees on the field, but as always there can never be enough.
I would recommend Bailey's to anyone who is looking for an affordable scenario with good paint prices.
