Help with time period

[Jarrod M]

A small group of us have been toying with the idea of doing a roman group but really have no definate time frame yet. Are thinking of a scorpion crew as a couple of us are keen to make one (and 3 or 4 guys trying to portray a legion is a bit silly). I would like to make a segmentata, so what would be a resonable time, and i guess place, to do.
Any help appreciated ,have had a look around the site and the legioxx site.

And there are no roman groups nearby, theres one in sydney 10hrs away and I think theres a local hopilite group.
