I have done a couple of series caches. I did "Route 2 Mystery Tour" by bike that took me 3 days and I did the "Wild Bunch" as a day trip. I've found that I really enjoyed doing these.
There is the "Mainely Rose" Series that will take me a number of days, so that will have to wait for the spring. Are there any other series out there that I should look at and can be made into a loop bike tour? Even if it's not a loop (Route 2 series wasn't) I could play with it.
Thanks all! Happy Autumn!
