Silverdale rocks the spot!! Just make sure there is someone there to take your money and load the machine. The price of their shells is the same as walmart or crappy tire so make sure you buy from them and not some bigass faceless corporation who doesn't give a crap about our sport!!
There almost always is but they are closed some days for a few hours. FYI, its fuc*ing cheap to blast away there, you will not regret it. We NEED to support clubs like this, this is what this sport is all about, freedom coupled with responsibility.
