I'm looking at setting my first cache and have a good idea or two for them (one trad, one multi). Can anyone give me pointers of common pitfalls or any other help further than whats on the 'hide a cache' page of geocaching.com. Also, if i want a cache to go live on a partiucular day can I do that, how far in advance do I need to submit it or should I just submit it near the day and hope? Thanks, J&B
