Number of Forums

[captainron19]

Looking to expand my current board system with discussions by each region in my state (NJ). My plan is to have each county listed (21 Total) - each one leading to a section of child forums listing towns located in each specific county (each town would act as its own forum under the county). Each county may have anywhere from 20 - 30 towns listed so that right there would give me a total of 600 forums or so on the system.

My question is, at what point should I be worried about having too many forums thus possibly making the system unstable? As far as the rest of the board goes I only anticipate a few handfuls of other forums so I should definitely be under 1,000 forums.

Any input would be appreciated.
